Susan wants to throw a party for her mom. She is planning on having 30 guests. For dinner she is making a recipe that makes 2 servings each. Each batch of the recipe calls for 4 potatoes and 1 teaspoon of salt. A potato costs $.10 and a container of salt costs $2 at the supermarket. If each container of salt has 5 teaspoons, how much money will Susan spend on food?

Susan needs to make 30/2=

<<30/2=15>>15 batches of the recipe. Therefore, she will need 15*4=<<15*4=60>>60 potatoes. She will also need 1*15=<<1*15=15>>15 teaspoons of salt. Thus she will have to buy 15/5 =<<15/5=3>>3 containers of salt. Therefore, she will spend 60*$.1=$6 on potatoes and 3*$2=$6 on salt. Thus, she will spend $6+$6=$<<6+6=12>>12 on food. #### 12 Joan is at the grocery store. She has a total of $60 to spend. She is going to purchase 2 containers of hummus, which are $5 each. She is going to purchase chicken for $20, bacon for $10, and vegetables for $10. She wants to purchase apples which are $2 each. With her remaining money, how many apples can she purchase? The total cost of the hummus is 2 * $5 = $<<2*5=10>>10 The total cost of the chicken, bacon, and vegetables is $20 + $10 + $10 = $<<20+10+10=40>>40 The remaining money she has is $60 - $10 - $40 = $<<60-10-40=10>>10 The amount of apples she can purchase is $10 / $2 = <<10/2=5>>5 #### 5 Lenny bought 20 boxes of pens. Each box contained 5 pens. She gave 40% of the pens to her close friends and one-fourth of what's left to her classmates. How many pens were left for Lenny? Lenny has 20 x 5 = <<20*5=100>>100 pens. She gave her close friends 100 x 40% = <<100*40*.01=40>>40 pens. So, 100 - 40 = <<100-40=60>>60 pens were left. Half of 60 is 60/4= <<60/4=15>>15 pens. Thus, Lenny has 60 - 15 = <<60-15=45>>45 pens left. #### 45 Josh has 18 yards of ribbon that is to be used equally to 6 gifts. If each gift will use 2 yards of ribbon, how many yards of ribbon will be left? The 6 gifts will use 6 x 2 = <<6*2=12>>12 yards of ribbon. So, 18 - 12 = <<18-12=6>>6 yards of ribbon will be left. #### 6 A dietitian ate three-fourths of her lunch during her lunch break. If the total amount of food she had prepared for lunch had 40 calories, and the recommended calorie intake by the FDA is 25, how many more calories than the recommended amount did she eat? A dietitian ate three-fourths of her lunch during her lunch break, containing 3/4*40=<<3/4*40=30>>30 calories. If the recommended calorie intake by the FDA is 25, the dietitian ate 30-25=5 more calories than the recommended amount. #### 5 Brenda picks 250 peaches. When she sorts through them, only 60% are fresh, and Brenda has to throw 15 away for being too small. How many peaches does Brenda have left? First find how many of the peaches are fresh, which is 250 peaches * 60% = <<250*60*.01=150>>150 peaches. Then, subtract the number Brenda throws away after the fresh count, which is 150 peaches - 15 peaches = <<150-15=135>>135 peaches. #### 135 Megan is delivering meals on wheels. Out of her 30 clients, 7 need vegan meals, 8 need kosher meals, and three people need meals that are both vegan and kosher. How many meals does Megan deliver that are neither kosher nor vegan? First, add the number of kosher meals to the number of vegan meals: 7 meals + 8 meals = <<7+8=15>>15 meals Then subtract the three meals that are both kosher and vegan since they got counted twice: 15 meals - 3 meals = <<15-3=12>>12 meals Finally, subtract that number from the total number of meals to find the number of meals that are neither kosher nor vegan: 30 meals - 12 meals = <<30-12=18>>18 meals #### 18 There were 40 kids on Lake Pleasant. A fourth of the kids went tubing, but only half of the tubers went rafting. How many of the kids who joined the rafting excursion were also on the tubing excursion? 40/4 = <<40/4=10>>10 kids went tubing. 10/2 = <<10/2=5>>5 kids went rafting and tubing. #### 5 In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether? Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12/2 = <<12/2=6>>6 commencement addresses. The two of them gave 6+12 = <<6+12=18>>18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12+10 = <<12+10=22>>22 commencement addresses. The three of them gave 22+18 = <<22+18=40>>40 commencement addresses. #### 40 Bill put his french fries in the oven after it finished heating. The recommended time was 5 minutes for them to be fully cooked. He put them in for 45 seconds. How many seconds remained? Each minute last 60 seconds, so that means for the fries to be fully cooked Bill needs to cook them for 5*60=<<5*60=300>>300 seconds Since Bill had the fries in the oven for 45 seconds so far, that means they need to stay in the oven for another 300-45= <<300-45=255>>255 seconds. #### 255
