Question

Faith wants to add a 20% tip to a $56 restaurant bill. How much will Faith pay including the tip?

Answer 1

$67.2

Explanation:

Given:

• Price = $56
• Tip = 20%

∴ Equation: Price + Tip = Total

• ⇒ 56 + (20/100 × 56) = Total

Simplify the equation to obtain the total:

• ⇒ 56 + (20/100 × 56) = Total
• ⇒ 56 + (20/50 × 28) = Total
• ⇒ 56 + (20/25 × 14) = Total
• ⇒ 56 + (4/5 × 14) = Total
• ⇒ 56 + (56/5) = Total

Convert the expression in the parenthesis into decimals:

• ⇒ 56 + (56/5) = Total
• ⇒ 56 + (11.20) = Total

Open the parenthesis and simplify:

• ⇒ 56 + 11.20 = Total
• ⇒ $67.2 = Total

Faith will pay (including the tip) $67.2.

Answer 2
