Question

Kayla has $45 and wants to buy three shirts that are originally priced at $18 each. They are on sale for 20% off. After applying 5% tax, does Kayla have enough money to purchase the three shirts

Answer 1

Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.

Step-by-step explanation:

Start by finding the price of one shirt on sale.

$18*0.2$

This equals 3.6 which is how much will be deducted from the original price.

One shirt costs $18-3.6$ when its 20% off.

This is equal to $14.40.

Since she wants to buy 3 of them we just multiply the $14.40 by 3.

$14.4*3=$

This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.

To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.

$43.2*1.05=$

This means the total price of Kayla's purchase will be $45.36.

This is over her $45 she has so she can not buy it.
