Question and rationale: The question is: Ronald can grill 15 hamburgers per session on his new grill. He needs to cook 115 hamburgers in total for tonight's party. He has already cooked 40 hamburgers. How many more sessions will it take Ronald to finish cooking all 115 hamburgers?
Step-by-step reasoning process: He has to cook 115 hamburgers and has already cooked 40 so he needs to cook 115 - 40 = 75 more hamburgers. He can only cook 15 hamburgers at a time so that means he has to cook 75 / 15 = 5 more cooking sessions.

Question and rationale: The question is: A woman needs to buy 16 oz of butter for a dessert recipe. She can either buy a single 16 oz package of the store-brand butter for $7, or she can buy an 8oz package of store butter for $4 and use a coupon to get an additional two 4 oz packages that normally sell for $2.0 each at a 50% discount (which is applied to each 4oz package separately). What is the lowest price she can pay for the 16 oz of butter she needs?
Step-by-step reasoning process: If she uses the coupon, she will pay 2 * 0.5 = $1 for each 4oz package. Thus, she will pay 4 + 2 * 1 = $6 in total for the 8oz package and the two 4oz packages she needs to reach 16 oz of butter when using the coupon. Therefore, the lowest amount she can pay is $6, as this is cheaper than the $7 price for a 16 oz package.

Question and rationale: The question is: Lucy works in a pet shop. She can clean 2 aquariums in 3 hours. If Lucy is working 24 hours this week, how many aquariums could she clean?
Step-by-step reasoning process: We know how many aquariums Lucy can clean in a 3 - hour increment. This week, Lucy will work for 24 / 3 = 8 increments. Lucy can clean 2 aquariums per increment, so she can clean 2 x 8 = 16 aquariums.

Question and rationale:
The question is: The GooGoo brand of clothing manufactures two types of shirts, one with 3 buttons and the other with 5 buttons. A large department store ordered GooGoo to manufacture 200 of each type of shirt. How many buttons will the GooGoo brand use to manufacturer all of the shirts for this order?
Step-by-step reasoning process: To make 200 of the first type of shirt, they will need 200 * 3 = 600 buttons. To make 200 of the second type of shirt, they will need 200 * 5 = 1000 buttons. To manufacture 200 each of both types of shirts, they will need to use 600 + 1000 = 1600 buttons.
