Part A: Write an equation to represent this situation, using s to represent the cost of one shirt. (Assume there is no sales tax where Mr. Jackson lives.)

Equation: __________________

Part B: What was the cost of one shirt? Show your work.

One shirt cost _________.

Answer 1

Part A :3 x +15 =52.50

Part B: one shirt cost: $12.5

Explanation:

Hi, to answer this question we have to write an equation:

The cost of 3 shirts (3x) and an umbrella ($15) equals $52.50.

Mathematically speaking:

Part A:

3 x +15 =52.50

Where:

x = price of each shirt

Part B:

Solving for “x”:

3 x +15 =52.50

3 x =52.50-15

3 x =37.5

x = 37.5 /3

x= 12.5

Each shirt costs $12.5
