A voice coach charges $165 for 1.5 hours of work. Which proportion can be used to find x, the number of dollars the voice coach charges for 4 hours of work?(1 point)
x/4 =1.5/165
x/165 = 3.5/2.5
x/165 = 1.5/4
x/4 = 165/1.5
To find the proportion, we can set up the ratio:
x/4 = 165/1.5
Cross-multiply to solve for x:
1.5x = 4 * 165
1.5x = 660
x = 660 / 1.5
x = 440
Therefore, the voice coach charges $440 for 4 hours of work.
The correct proportion that can be used to find x is:
x/4 = 165/1.5
