Question

A bakery is offering a promotion where a customer can buy a dozen

cookies for $9.50. Normally, the cookies cost $1.25 each. By how
much is the cost of the cookies discounted? Round to the nearest
whole percent, if necessary.

Answer 1

The cookies are discounted by 37%.

Explanation:

Given that:

Promotional price of cookies = $9.50

Normal price = $1.25 per cookies

Cost of dozen = 1.25*12 = $15

Discount amount = 15 - 9.50 = $5.50

Percent discount =
`(Discount\ amount)/(Normal\ cost)*100`

Percent discount =
`(5.5)/(15)*100 = 0.366*100`

Percent discount = 36.6%

Rounding off to nearest whole percent

Percent discount = 37%

Hence,

The cookies are discounted by 37%.
