Stephanie wants to buy s tomato plants, and 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.

If Stephanie buys 6 tomato plants, and Diego buys 4 tomato plants, how much will they pay after using the coupon?

A
$21

B
$45

C
$85

D
$243

Answers

Answer:

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

B.$45

explanation: each plant costs 7 dollars so...
6x7=42
4x7=28
42+28=70
70-25=45
