$Sales\ Price = \$9.60$

Step-by-step explanation:

Given

$Price = \$24.00$

$Discount = 60\%$

Required

Determine the sales price

First, we calculate the discount price

$Discount\ Price = Price * Discount$

$Discount\ Price = \$24.00 * 60\%$

$Discount\ Price = \$14.4$

The sales price is then calculated by subtracting the discount price from the original price of the item

$Sales\ Price = Price - Discount\ Price$

$Sales\ Price = \$24.00 - \$14.40$

$Sales\ Price = \$9.60$
