Answer:
B
Explanation:
To find the number of extra flowers ordered, we can start by forming an equation based on the total amount paid by the customer.
Let the number of extra flowers be n.
Total paid
= cost of standard arrangement +(number of extra flowers)(cost per additional flower)
= $25 +n($1.25)
Given that the customer paid $45,
25 +1.25n= 45
Now that we have formed the equation, let's solve for n.
Subtract both sides by 25:
1.25n= 45 -25
1.25n= 20
Divide both sides by 1.25:
n= 20 ÷1.25
n= 16
