A blueberry muffin is on sale for 5% off. It's sale price is $1.90. What was the original price?
Tatiana [17]

Answer:

The original price was $2.

Step-by-step explanation:

The muffin is on sale for 5% off. This means it is being sold for 95% of its original price.

Its sale price is $1.90. This means that 95% of its original price is 1.90.

Let's set up an equation.

95% of original price is $1.90.

0.95 • x = 1.90

Divide both sides by 0.95 to isolate x.

x = 2

The original price was $2.

Hope this helps!
