Explanation:

Problem 8:

Step1: Understand markup formula

Selling price \( = \) Cost price \( + \) (Markup percentage \( \times \) Cost price). Here, cost price \( = \$20 \), markup percentage \( = 40\% = 0.4 \).

Step2: Calculate markup amount

Markup amount \( = 20 \times 0.4 = 8 \).

Step3: Calculate selling price

Selling price \( = 20 + 8 = 28 \).

Step1: Understand markdown formula

Sale price \( = \) Selling price \( - \) (Markdown percentage \( \times \) Selling price). Here, selling price \( = \$952 \), markdown percentage \( = 20\% = 0.2 \).

Step2: Calculate markdown amount

Markdown amount \( = 952 \times 0.2 = 190.4 \).

Step3: Calculate sale price

Sale price \( = 952 - 190.4 = 761.6 \).

Step1: Understand sales tax formula

Total price \( = \) Item price \( + \) (Sales tax percentage \( \times \) Item price). Here, item price \( = \$22 \), sales tax percentage \( = 5\% = 0.05 \).

Step2: Calculate tax amount

Tax amount \( = 22 \times 0.05 = 1.1 \).

Step3: Calculate total price

Total price \( = 22 + 1.1 = 23.1 \).

Answer:

\$28
