The correct answer is B
325-45=280
8x35=280
First,
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550
then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55
127,822.50 * .04 = 5112.90
trade discount = 14950 + 6727.50 + 5112.90
26790.40
hope this help
she needs 10 feet because 6 2/3 yard converted into feet is 20 and 30-20=10
F(x)=-2x+4x-7
f(x)=2x-7
now f(-4)=2(-4)-7=-8-7=-15
So it will be -15
