Question

A musician performed at three local fairs. At the first he doubled his money and spent

Answer 1

Answer:

The Musician had $29 before  performing at the fairs

Step-by-step explanation:

Let the  initial amount musician has be x

At the first musician doubled his money and spent

$30 , this can be written as

2(x) -30---------------------------------(1)

At the second he tripled his money and spent $54.

3(2x -30) - 54

=> 6x-90-54

=> 6x- 144--------------------------------(2)

At the third, he quadrupled his  money and spent $72

4( 6x- 144) - 72

24x - 576 - 72

24x -648-------------------------------(3)

At-last he had $48

24x -648 = 48

24x  = 48+ -648

24x  =696

x = $\frac{696}{24}$

x = 29
