Find the selling price of a $7.50 agenda book with a 15% discount. Round to the nearest cent when necessary.

The selling price of the agenda book is $6.38 to the nearest cent.

Step-by-step explanation:

Assume that the cost price of the agenda book is 100%

∵ The discount is 15%

∵ The selling price = the cost price - discount amount

∴ The selling price = 100% - 15%

→ That means the selling price is 85% of the cost price

∵ The cost price = $7.50

∴ The selling price = 85% × 7.50

→ Change 85% to a number by divide it by 100

∴ The selling price = × 7.50

∴ The selling price = 6.375

→ Round it to the nearest cent (2 d.p)

∴ The selling price = $6.38

∴ The selling price of the agenda book is $6.38 to the nearest cent.
