Answer 1

PART A

write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. d-(d-5).10 = 27.5 (if you put d in as 30!)

PART B

write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. d-(d*.10)-5 =22 (if you put d in as 30!)

PART C

which order will save marina more money? explain your reasoning.

d-(d*.10)-5 This equals less! if you put in 30 as an example

So, A) d-(d-5).10 B) d-(d*.10)-5 C) d-(d*.10)-5
