Question

Write a Let" statement for the unknown, write an equation, and solve the equation. 11. Jane bought a number of records for $7 each. She then spent $3 more for a poster. If she spent a total of $24, how many records did she buy?

Answer 1

Let n = number of records.

Each record costs $7, so n records cost 7n.

She then spent $3, so the total spent is 3n + 3.

She spent a total of $24, so 3n + 3 must equal 24. That gives us the following equation.

7n + 3 = 24

Subtract 3 from both sides.

7n = 21

Divide both sides by 7.

n = 3

Answer: She bought 3 records.
