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:
- Discount = 10% = 0.10 (decimal form, 10/100 =0.1)
- Cost after discount: $4.50
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

Answer: The regular or normal price of the nut - free granola bars is $5.00
Step-by-step explanation:
Firstly, a discount simply refers to the reduction in the regular or normal price of a commodity or service.
In this case, Trey purchased his preferred nut - free granola bars but he did not buy the nuts at the usual price. The price or cost of the nut - free granola bars were reduced by 10 percent.
Now, let us denote the regular or normal cost of the nut - free bars as $x.
Since the original price was reduced by 10%, then:
10/100 × x = x/10 (This is 10% of the cost of the nut - free bars)
Let us now subtract 10% of the original cost of the nut - free granola bars from the regular cost of the bars. This will now be equal to the price that Trey finally purchased the bars.
x - (x/10) = $4.50
All we need to do now is to solve for "x" and we will discover the original cost of the bars.
(10x - x)/10 = 4.50
9x/10 = 4.50
9x = 4.50 × 10
9x = 45
x = 45/9
x = $5 (This is the normal price of the bars).
