So b is the correct answer
We have been given the expression
We have to write this expression in the form 
In order to write the given expression in this form, we can use some exponent property.
On using the property (1), we have
Now, on using the property (2), we get
Therefore, the simplified form of the given expression is
60%
Solve by creating a proportion
27/45 = x/100
Cross multiply to get 2700=45x

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
