Answer:

B - 2 hours

Step-by-step explanation:

find the rate for each scenario until you find one that matches.

for A 1 hour:

Ben charges (15.50×1hour) = 15.50

Cathie charges (9.25 × 1 hour) + 12.50 flat fee = 21.75

THESE DO NOT MATCH

so you do B 2 hours:

Ben charges 15.50× 2hours = 31

Cathie charges (9.25 × 2hours) + 12.50 flat fee = 31

THESE MATCH SO THIS IS THE ANSWER

If you continue like this for 3 hours and 4 hours the values don't match. so the only answer is B.
