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 = 
x = 29
Answer:
72

Answer:
Surface area: 384in
Step-by-step explanation:
To find the surface area, you calculate the area of one side of the cube.
8 x 8 = 64
Once you get the area of one side of the cube, you multiply your new number by the number of sides in the cube. A cube has 6 sides, so you would multiply the area by 6.
64 x 6 = 384
Therefore, your surface area is 384in
