Question

Ms. Jacobs is a photographer. For each job she charges $135 for the first hour she works and $100 for each additional hour. Ms. Jacobs charged a total of $535 for a job on Friday. Which equation can be used to determine h, the number of additional hours she worked on this job? MI - A 135h + 100 = 535 B 135 + h + 100 = 535 SI - C 135 + 100h = 535 PSA - D 135h = 535 + 100 is​

Answer 1

The answer is C, 135 + 100h = 535.

Explanation:

H can't be multiplied by 135, since that's only for one hour. That value never changes, so it can't be A. It's not B because that implies that she starts out by charging $235 for the first hour, plus the # of additional hours, which doesn't make sense. And it's not D because the total amount of $ that she receives must EQUAL 535, but there is another number on the same side with 535. Therefore, the only answer that remains is C.

P.S. She worked 4 additional hours.
