John used his MasterCard credit card to purchase groceries for $75.63, gas for $93.45, and a video game for $61.93 this month. How much should his payment to his credit card company be in order for him to avoid interest charges on these purchases?

answer: first option i.e. 'a' is correct.

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

so, it becomes,

hence, first option 'a'   is correct.
