Percentages in the Real World Examples Page 5

Sweet! Jeans at American Shmeagle are 40% off. How much will you pay for a pair of jeans that were originally $80? (don't forget the 9.25% sales tax)

Look Out: always calculate the discount before adding in the sales tax

First calculate the 40% discount. You can do this by translating it into an equation:

40% (0.40) of (multiply) $80 is (equals) what (x)?

Solve the equation.

And subtract that from $80.

Now it is time to add in the sales tax: 9.25% of $48 is what?

9.25% (0.0925) of (multiply) $48 is (equals) what (x)?

Solve the equation.

This is the sales tax.

Add the sales tax to the sale price.

The grand total for the jeans is: $52.44
