Alice has two part-time jobs. One job she makes 8 dollars per hour and the other she makes 12 dollars per hour. One week she made worked 30 hours and made 268 dollars. How many hours at each job?

Answer 1

X Hrs @ $8 per hr.
(30-8) Hrs @ $12 per hr.

8x + 12(30-x) = $268
8x + 360 - 12x = 268
-4x = 268-360 = -92

X = 23 Hrs. @ $8 per hr.
30-23 = 7 Hrs @ $12 per hr.

Answer 2

Correction:
(30-X) Hrs. @ $12 per Hr.
NOT (30-8).
