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
Answer:
B
Step-by-step explanation:
In order to answer the question we need the lengths to do the math.
d1 = 51(t)
d2 = 71(8 - t)
d1 + d2 = 508
and now you just have to solve for t.
Multiply both by -1: 113.75-112=1.75
multiply answer by -1: -1.75
