Answer:
(V - 13)/4 grapes
where V is the number of grapes bought.
Explanation:
Given that Mae bought some grapes and used 13 of them. She split apart the remaining grapes into 4 equal parts to eat for snacks each day during the week. We may take each statement in parts. Beginning with Mae bought some grapes and used 13 of them, if the number of grapes she bought is V, then she would have left
= V - 13 grapes
If She split apart the remaining grapes into 4 equal parts to eat for snacks each day during the week it means that each day, she will eat
= (V - 13)/4 grapes
