enter your answer in the box.

Step-by-step explanation:

so she earns 9.75% commission on each mattress

turn ur percent to a decimaland multiply that by the cost of the mattress and that will give u her commission.

0.0975(2400) + 0.0975(3200) + 0.0975(1900) + 0.0975(800) =

234 + 312 + 185.25 + 175.50 =

906.75 <=== her total commission

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
