Answer:

1) The discount is $4.05

The sale price is $18.45

2) The discount is $10

The sale price is $30

3) The discount is $2.6

The sale price is $23.4

Step-by-step explanation:

1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.

Actual Price= $22.50

Discount = 18%

Finding discount:

$18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05$

So, the discount is $4.05

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=22.50-4.05\\Sale\:Price=18.45$

The sale price is $18.45

2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.

Actual Price= $40.00

Discount = 25%

Finding discount:

$25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10$

So, the discount is $10

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=40.00-10\\Sale\:Price=30$

The sale price is $30

2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.

Actual Price= $26.00

Discount = 10%

Finding discount:

$10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6$

So, the discount is $2.6

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=26.00-2.6\\Sale\:Price=23.4$

The sale price is $23.4
