Question

Michael works two part time jobs for a total of 23 hours a week. Job A pays 6.20 per hour and job B pay 6.60 per hour. How many hours did he work at each job the week that he made 148.20?

Answer 1

assume he worked x hours at Job A, y hours at Job B

6.2x + 6.6y = 148.2
x + y = 23

Answer 2

how many hours for job a and b?

Answer 3

6.2x + 6.2y = 6.2*23

6.2x + 6.6y = 148.2

0.4y = 148.2 - 6.2*23

y = 14

so x = 9

Answer 4

Answer 5

If Michael wirks t hours at job An then he works
23 - t houre at job B. Total earnings for job A is
6.2t dollars, and for job B it's 6.6(23-t) dollars. In terms of t, his total from both jobs that week is
6.2t + 6.6(23-t) = 151.8 - .4t = 148.2.
.4t = 3.6
t = 36/4 = 9.
He worked 9 hours at job A and 14 hours at job b.
