Answer:
Step-by-step explanation:
Mike's total pay is the result of dividing a fixed amount of time between two jobs. The total hours and the total pay give us two relations that let us solve for the time at each job.
Let x represent the number of hours Mike works at Job B. Then 56-x is the number of hours he works at Job A. His total pay for both jobs is ...
8x +7(56 -x) = 410
x +392 = 410 . . . . . . simplify
x = 18 . . . . . . . . . subtract 392
56 -x = 38 . . . find Job A hours
Mike works 38 hours at Job A, and 18 hours at Job B.
