Answer:
d. 4
Step-by-step explanation:
total amount Frank is willing to pay is 1000 + 850 + 700 + 500 = $3050
given the price of a class cost $750
therefore,
total number of classes he will be able to take = total amount frank is willing to pay/ price per class
so, 3050/750
= 4.067
approximately = 4
