Kristi bought a mattress that was on sale for $350. Original price of the mattress was $1150. What is the dollar amount of the discount? What is the discount rate as a percentage (rounded to the nearest tenth) ?

Step-by-step explanation:

A.) Sale = $350

Original price = $1,150

Dollar amount of the discount = Original price - Sale price

Discount (in dollars) = 1,150 - 350

Discount (in dollars) = $800

B.)

To calculate discount rate as a percentage, Divide the dollar amount of discount by the original price then multiply the result by 100

Percentage discount = (800/1,150) * 100

= 0.695652 * 100

= 69.56552%

To the nearest tenth is to the nearest 1 decimal place = 69.6% discount
