Amusician performed at three local fairs. at the first he doubled his money and spent
$30. at the second he tripled his money and spent $54. at the third, he quadrupled his
money and spent $72. in the end he had $48 left. how much did he have before
performing at the fairs?

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 =

x = 29

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
