Shella works 8 hours per day on monday, wednesday and friday and 6 hours per day on tuesday and thursday. she doesn't work on the weekend and she earned $324 per week. how much does she earn in dollars per hour

Numbers of hours = 3*8 + 2*6 = 24+12 = 36 hours

Dollars for 36 hours = $324

dollars for 1 hour = $324/36 = $9

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
