Answer: The regular price of the granola bars were $5 each.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
- <em>Discount = 10% = 0.10 (decimal form, 10/100 =0.1)
</em>
- <em>Cost after discount: $4.50
</em>
So, the original price of the granola bar (x) multiplied by 0.9 ( since 100% is the full price,1- 0.1= 0.9) equals to 4.50 (cost after discount)
Mathematically speaking
x (1- 0.1) = 4.50
x 0.9 =4.50
x = 4.50/0.9
x= 5
