In this activity, you'll create a linear equation to represent a real-world situation and then use it to solve a problem. Read the situation, and then answer the questions that follow.

Price of copy = $5

Step-by-step explanation:

Situation:

Tommy purchases five copies and five pencils. He gives $130 to the shopkeeper.

If the price of a pencil is $13, find the price of a copy.

Assume

Number of copy = 5

Number of pencil = 5

Price of copy = x

Price of Pencil = $13

So,

5(x) + (5)(13) = 130

6(x) + 65 = 130

x = 5

So,

Price of copy = $5
