Question 264211: Anna worked two part-time jobs last week. The first job paid $11 an hour, and the second job paid $14 an hour. She worked a total of 26 hours last week and earned $319.
How many hours did Anna work at the first job?
Write an equation you can use to answer this question. Let x be the number of hours worked at the first job.
Use your equation to solve the problem.
You can put this solution on YOUR website! 11x+14(26-x)=319
11x+364-14x=319
-3x=319-364
-3x=-45
x=-45/-3
x=15 hours were worked @ the first job.
26-15=11 hours were worked @ the second job.
Proof:
11*15+14*11=319
165+154=319
319=319
