Mr. Martin’s math test, which is worth 100 points, has 35 problems. Each problem is worth either 5 points or 2 points.
makkiz [27]

Answer:

A

Step-by-step explanation:

a = 10 X 5 = 50, 25 X 2 = 50 = 100

B = 15x5 = 75, 20 x 2 = 40, = 105

C = 20 x 5 = 100, already at 100 (so immediately wrong)

D: 25 x 5 = 125, already larger than 100 (so immediately wrong)

Therefore A is the only correct option, hop i helped you!
