The card shop has two boxes of cards. The first box contains cards that cost $1.25 each. The second box contains cards that cost $1.75 each. A boy then comes in and buys 6 cards from each box. What was the total cost, in dollars, of the cards he bought?

The cost of one card from each box in total is 1.25+1.75=

<<1.25+1.75=3>>3 dollars. The total cost of cards the boy bought is 3*6=<<3*6=18>>18 dollars. #### 18 Gina has two bank accounts. Each account has a quarter of the balance in Betty's account. If Betty's account balance is $3,456, what is the combined balance of both Gina's accounts? Each of Gina's account has $3456 / 4 accounts = $<<3456/4=864>>864/account Her combined account balance is therefore $864 + $864 = $<<864+864=1728>>1728 #### 1728 Riku has 25 times more stickers than Kristoff. If Kristoff has 85 stickers, how many stickers does Riku have? If Kristoff has 85 stickers, Riku has 25 * 85 stickers = <<85*25=2125>>2125 more stickers. The total number of stickers Riku has is 2125 stickers + 85 stickers = <<2125+85=2210>>2210 stickers #### 2210 Lily has 5 lottery tickets to sell. She sells the first ticket for $1. She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive? The second ticket sold will cost $1 + $1 = $<<1+1=2>>2. The third ticket sold will cost $2 + $1 = $<<2+1=3>>3. The fourth ticket sold will cost $3 + $1 = $<<3+1=4>>4. The fifth ticket sold will cost $4 + $1 = $<<4+1=5>>5. The total money collected is $1 + $2 + $3 + $4 + $5 = $<<1+2+3+4+5=15>>15. After taking profit, the total prize money will be $15 - $4 = $<<15-4=11>>11. #### 11 Matt buys a massager. At the lowest setting, it vibrates at 1600 vibrations per second. At the highest setting, it vibrates 60% faster. Matt uses it for 5 minutes at the highest setting. How many vibrations does he experience? At the highest setting, it vibrates 1600*.6=<<1600*.6=960>>960 vibrations per second faster than the lowest setting So it vibrates at 1600+960=<<1600+960=2560>>2560 vibrations per second Matt uses it for 5 minutes so that is 5*60=<<5*60=300>>300 seconds That means he experienced 2560*300=<<2560*300=768000>>768,000 vibrations #### 768000 John wants to finish a show in 5 days. There are 20 episodes and they are each 30 minutes long. How many hours does he have to watch a day? He wants to watch 20*30=<<20*30=600>>600 minutes So he needs to watch 600/60=<<600/60=10>>10 hours That means he needs to watch 10/5=<<10/5=2>>2 hours a day #### 2 There were 18 students assigned in a minibus for a field trip. Eight of these students were boys. On the day of the field trip, the number of girls and boys was the same since some of the girls were not able to join the trip. How many girls were not able to join the field trip? 8 boys + 8 girls = <<8+8=16>>16 students joined the field trip. Thus, 18 - 16 = <<18-16=2>>2 girls were not able to join the field trip. #### 2 Bran's tuition fee is $90. He does a part-time job that pays him $15 per month and he has a scholarship that takes care of 30% of his tuition fee. If he needs to pay his tuition fee within 3 months, how much does Bran still need to pay? Bran's scholarship pays $90 x 0.30 = $<<90*0.30=27>>27 to his tuition fee. So, the total amount he still needs to pay is $90 - $27 = $<<90-27=63>>63. And Bran will be able to earn $15 x 3 = $<<15*3=45>>45 after working for 3 months. Therefore, the total amount he still needs to pay is $63 - $45 = $<<63-45=18>>18. #### 18 John decides to get gym memberships so he can get in shape. The gym close to his house is close but doesn't have everything he wants so he gets two different gym memberships. The cheap one costs $10 a month and has a sign-up fee of $50. The second gym is 3 times more expensive and it has a sign-up fee of 4 months membership. How much total did he pay in the first year for gym membership? The cheap gym cost 10*12=$<<10*12=120>>120 for monthly fees So the total cost was 120+50=$<<120+50=170>>170 The more expensive gym cost 3*10=$<<3*10=30>>30 per month That means the sign-up fee was 30*4=$<<30*4=120>>120 The monthly fees for the expensive gym comes out to 30*12=$<<30*12=360>>360 per year So the total cost for the expensive gym was 360+120=$<<360+120=480>>480 So his total cost was 480+170=$<<480+170=650>>650 #### 650 Jim collects model cars, and he has 301 models total. Jim has 4 times as many Buicks as Fords, and 3 more than twice the number of Fords than Chevys. How many Buicks does Jim have? Let x represent the number of Chevys Fords:3+2x Buicks:4(3+2x)=12+8x Total:x+3+2x+12+8x=301 11x+15=301 11x=286 x=<<26=26>>26 Buicks:12+8(26)=220 #### 220
