PLEASE HELP ME ANY ANSWERS I WILL ACCEPT IT PLEAS) Marina wants to purchase a rosebush for d dollars at a garden store. She has a coupon good for $5 off her purchase, and the store is having a 10% off sale.
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.
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.
PART C
which order will save marina more money? explain your reasoning.

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

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
