Stephanie wants to buy s tomato plants. diego wants to buy d tomato plants. each plant costs $7. stephanie will use a coupon that gives them $25 off the total cost of all their plants. which expression represents the total cost of all the plants with the discount?

Required Expression : 7·(s + d) - 25

Step-by-step explanation :

Cost of each plant both buys = $7

No. of plants Stephanie wants to buy = s

Total cost of plants bought by Stephanie = 7·s

No. of plants Diego wants to buy = d

Total cost of plants bought by Diego = 7·d

Total cost = 7·s + 7·d

                 = 7·(s + d)

Discount applied through coupon = $25

So, Total cost of all their plants with discount = 7·(s + d) - 25

a negative exponent is translated as follows:

so, we have

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
