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
