Alfred likes to save $1,000.00 over 12 months for his Christmas shopping. He has $100.00 left over from last year's holiday to put towards this year's goal. How much money does Alfred now need to save each month in order to reach his goal in 12 months?

He wants to save $1,000.00 and he has $100.00 left over so he still needs to save 1000-100= $

<<1000-100=900.00>>900.00 He wants to save $900.00 over 12 months so that means he needs to save 900/12 = $<<900/12=75.00>>75.00 per month #### 75 Victoria had $500. She went to the market and bought 2 packets of rice each at $20, 3 packets of wheat flour each at $25, and 1 soda at $150. What was her remaining balance? In total, she spent 2*$20 + 3*$25 + $150 = $<<2*20+3*25+150=265>>265 Thus her remaining balance is $500 - $265 = $<<500-265=235>>235 #### 235 Roy spends 2 hours on sports activities in school every day. He goes to school 5 days a week. If he missed 2 days within a week, how many hours did he spend on sports in school that week? He goes to.school 5 days a week so if he misses 2 days within the week he was present for 5-2 = <<5-2=3>>3 days He spends 2 hours every day for a total of 2*3 = <<2*3=6>>6 hours #### 6 James has to refuel his plane. It used to cost $200 to refill the tank. He got an extra tank to double fuel capacity. Fuel prices also went up by 20%. How much does he pay now for fuel? The cost to fill a tank went up 200*.2=$<<200*.2=40>>40 So it cost 200+40=$<<200+40=240>>240 to fill the tank That means he now pays 240*2=$<<240*2=480>>480 #### 480 John has 3 children. He and his wife are supposed to buy notebooks for their sons but they couldn't agree on how many to buy. So John bought 2 notebooks for each of his children and John's wife bought 5 notebooks for each of them. How many notebooks did they buy in total for their children? John bought 2 notebooks for his 3 children: 2 notebooks/child x 3 children = 6 notebooks. The father bought 6 notebooks. John's wife bought 5 notebooks for their three children: 5 notebooks/child x 3 children = <<5*3=15>>15 notebooks. The mother bought 15 notebooks. Now, the total number of notebooks is 6 notebooks +15 notebooks = <<6+15=21>>21 notebooks. #### 21 Hugo can fold a small box in 3 seconds and a medium one in twice that time. Tom can fold both the small and medium boxes in 4 seconds. If Hugo and Tom want to leave as early as possible, how long (in seconds) will it take them to fold 2400 small boxes and 1800 medium boxes? If it takes Hugo twice the amount of time to fold a medium box than a small box, then he needs 2*3 = <<6=6>>6 seconds for the medium box If Tom can fold either the small or medium box in 4 seconds, then he's faster at folding the medium box than Hugo because 4s < 6s If Hugo can fold the small box in 3 seconds, then he's faster at folding the small boxes than Tom because 3s < 4s Therefore Hugo should fold all small boxes and Tom should fold all the medium ones before doing the other size where they are slower If there are 2400 small boxes and Hugo can fold 1 box in 3 seconds, then it would take him 2400*3 = <<2400*3=7200>>7200 seconds to fold all boxes If there are 1800 medium boxes and Tom can fold 1 box in 4 seconds, then it would take him 1800*4 = <<1800*4=7200>>7200 seconds to fold all medium boxes Given that they need the same amount of time to fold all boxes, and are doing it simultaneously they will need 7200 seconds to fold all the boxes #### 7200 In one of the teacher's meetings, it was agreed that each class will contribute $90 for a school activity. The class of Miss Evans has $14 class funds and they decided to use it to lessen the contribution of each student. If the remaining amount will be divided among 19 students, how much will each student contribute? The 19 students will divide equally the remaining $90 - $14 = $76. So, each student will contribute $76 / 19 students = $<<76/19=4>>4/student. #### 4 Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied? The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25-$5 = $<<25-5=20.00>>20.00 He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40/1 = <<40/1=40>>40 1 oz servings The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20/40 = $<<20/40=0.50>>0.50 per serving #### 50 Martha needs to paint all four walls in her 12 foot by 16 foot kitchen, which has 10 foot high ceilings. Each wall needs one coat of primer and two coats of paint. If Martha can paint 40 square feet per hour, how many hours will it take her to paint the kitchen? There are two walls that are 12' X 10' and two walls that are 16' by 10'. First find the size in square feet of one 12' x 10' wall by multiplying the height and length: 12 ft * 10 ft = <<12*10=120>>120 sq ft Multiply that quantity by 2 since there are two 12' x 10' walls: 120 sq ft * 2 = <<120*2=240>>240 sq ft Then find the size in square feet of one 16' x 10' wall by multiplying the height and length: 16 ft * 10 ft = <<16*10=160>>160 sq ft Multiply that quantity by 2 since there are two 16' x 10' walls: 160 sq ft * 2 = <<160*2=320>>320 sq ft Now add the square footage of both sets of walls to find the total square footage Martha needs to paint: 240 sq ft+ 320 sq ft = <<240+320=560>>560 sq ft Now multiply that amount by 3 because Martha needs to add 3 coats: 560 sq ft/coat * 3 coats = <<560*3=1680>>1680 sq ft Finally, divide the total square footage by Martha's painting rate to find how many hours she needs to finish: 1680 sq ft / 40 sq ft/hour = <<1680/40=42>>42 hours #### 42 A box of ice cream bars costs $7.50 and contains three bars. 6 friends want to each eat 2 bars. How much money will that require per person? If 6 friends each want 2 bars, that's 6 friends * 2 bars = <<6*2=12>>12 bars needed. Each box contains 3 bars, so 12 bars / 3 bars per box = <<12/3=4>>4 boxes needed. A box is $7, so 4 boxes * $7.50 = $<<4*7.5=30>>30. There are 6 friends so $30 / 6 friends = $<<30/6=5>>5 per person. #### 5
