Answer:
15. Her commission is $10.72.
16a.-8x-24
b.27+63y
Step-by-step explanation:
15. $134 multiplied by the 8% that she makes from commissions is 134x0.08=10.72
16a. Expand -4(2x+6)
-4 times 2x is -8x
-4 times 6 is -24
put them together and get -8x-24
b. Expand 9(3+7y)
9 times 3 is 27
coefficient of y is 9 times 7 which equals 63
put them together and get 27+63y
