Answer:

$48 in 4 hr

Step-by-step explanation:

Let's set up two equal proportions and cross-multiply, putting the money on top and the hours on bottom.

[tex]\frac{72 dollars}{6 hr} = \frac{x dollars}{4 hr}[/tex]

Now we can cross-multiply:

72*4 = 6x

288 = 6x

x = 288/6 = $48

Answer:

$48

Step-by-step explanation:

Amount : hour

$72 : 6

$X : 4

4/6 = X/72

X = 72 × 4/6

X = 48
