Question: Lena has 16 candy bars. She needs 5 more candy bars to have 3 times as many as Kevin, and Kevin has 4 candy bars less than Nicole. How many more candy bars does Lena have than Nicole?
Answer with step-by-step thinking: Kevin has (16 + 5) / 3 = 7 candy bars. Nicole has 7 + 4 = 11 candy bars. Lena has 16 - 11 = 5 more candy bars than Nicole.
So the answer is 5.


Question: Nancy and Jason are learning to dance for the first time. Nancy steps on her partner's feet 3 times as often as Jason. If together they step on each other's feet 32 times, how many times does Jason step on his partner's feet?
Answer with step-by-step thinking: Let n be the number of times Nancy steps on her partner's feet and j be the number of times Jason does. We know that n = 3j and n + j = 32. Substituting the first equation into the second equation, we get 3j + j = 32. Combining like terms, we get 4j = 32. Dividing both sides by 4, we get j = 8.
So the answer is 8.


Question: Ephraim has two machines that make necklaces for his store. On Sunday the first machine made 45 necklaces. The second machine made 2.4 times as many necklaces as the first machine. How many necklaces were made in total on Sunday?
Answer with step-by-step thinking:
The second machine made 2.4 times as many necklaces as the first machine, so the second machine made 2.4 * 45 = 108 necklaces on Sunday. In total, 45 + 108 = 153 necklaces were made on Sunday.
So the answer is 153.
