Answer:
Of the 75 orders, 40 orders correspond to Rob and 35 orders correspond to Juan.
Explanation:
Given that Juan and Rob are selling cookie dough for a school fundraiser, having a total of 75 orders, of which 40 correspond to Rob, to determine how many orders correspond to Juan the following calculation must be performed:
75 - 40 = X
35 = X
Thus, of the 75 orders, 40 orders correspond to Rob and 35 orders correspond to Juan.
