Question

Callie wants to buy a new pair of jeans that

regularly costs $40. If the jeans are on sale
for 20% off, and sales tax is 7%, how much
will Callie pay for the jeans?

Answer 1

$34.24

Explanation:

First step I'd do is find how much it costs after the discount, then, after find the total with tax because it's taxed after the discount.

So to find the discounted price you simply multiply the discount by the original price then subtract the discount from the price to get the discounted price.

`40*0.20=8\\40-8=32`

So the discounted price without taxes is $32. Now to find the price with tax you do the same thing but instead of subtracting, you add it

`32*0.07=2.24\\32+2.24= 34.24`

So the total price Callie will pay for the jeans is exactly $34.24
