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
<u>THESE</u><u> </u><u>DO</u><u> </u><u>NOT</u><u> </u><u>MATCH</u>
so you do B 2 hours:
Ben charges 15.50× 2hours = 31
Cathie charges (9.25 × 2hours) + 12.50 flat fee = 31
<em><u>THESE</u></em><em><u> </u></em><em><u>MATCH</u></em><em><u> </u></em><em><u>SO</u></em><em><u> </u></em><em><u>THIS</u></em><em><u> </u></em><em><u>IS</u></em><em><u> </u></em><em><u>THE</u></em><em><u> </u></em><em><u>ANSWER</u></em>
If you continue like this for 3 hours and 4 hours the values don't match. <em><u>so the only answer is B</u></em><em><u>.</u></em>
