x dollars = first 8 hours

y dollars = each hour after the first 8 hours.

M + T + W + Th + F = 5 * 8 = 40 hours.

For 40 hours, he will be paid 5*x = 5x dollars.

He worked for: 8 + 11 + 9 + 10 + 9 = 47 hours.

Extra hours: 7

For 7 hours, he will be paid 7*y = 7y dollars.

Overall paid: 5x + 7y

Average: (5x + 7y)/5

=> x + 1.4y
