Question

Marley lost her tennis racket. She bought a new one for 30$. This is 6$ less than three times the price of her old one. How much did she pay for her old tennis racket?

Answer 1

$8

Explanation:

$30 is the new total

let's say x equals the price of the old racket

1. first you set the problem

• 30 = 6 - 3x

2. then you subtract 6 from both sides

• 24 = 3x

3. finally you divide by 3 from both sides

• 8 = x

there's your answer.
