PLEASE HELP ME ANY ANSWERS PLEAS I DONT UNDERSTAND THIS) 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

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: and

If we apply the coupon first, we have , because we are subtracting 5 dollars from the total price. Then, if we apply the discount, we get . It is a 10% discount, which means the price will end up being 90% of the original price, so we need to multiply the price by 0.9. To get the second equation, I distributed the 0.9 (multiplied it by both parts of the equation in parentheses) to get .

PART B:

If we apply the discount first, we get . Then, when we apply the coupon, we subtract 5 dollars from that price, getting .

PART C: Discount, then coupon.

To figure out which order will save more money, we look at the simplified equations for each order. In the first order, we end up subtracting 4.5 from , and in the second order, we end up subtracting 5 from . In the second order, we are subtracting more money, so the price will be lower and she will save more money.
