Question

write an algebraic expression to represent the situation.
you have a coupon for $5 off your total bill at mamas meals on main.
a. how much will you pay after using the coupon if your bill was b dollars?

b. evaluate your expression to calculate the amount you will pay if your bill was $23.45 $
$54.83 $

Explanation:

Part A: Algebraic Expression

Step1: Define the variable

Let \( b \) be the total bill in dollars. The coupon is for \$5 off, so we subtract 5 from the bill.

Step2: Write the expression

The amount paid after using the coupon is \( b - 5 \).

Step1: Substitute \( b = 23.45 \) into the expression

We use the expression from Part A, \( b - 5 \), and substitute \( b = 23.45 \).

Step2: Calculate the result

\( 23.45 - 5 = 18.45 \)

Step1: Substitute \( b = 54.83 \) into the expression

Use the expression \( b - 5 \) and substitute \( b = 54.83 \).

Step2: Calculate the result

\( 54.83 - 5 = 49.83 \)

Answer:

\( b - 5 \)

Part B: Evaluation for \$23.45
