Question

Anita earns $72 every 6 h to fix bicycles. How much money will she earn in 4 h if she is paid at the same rate?

Answer 1

$48 in 4 hr

Explanation:

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

`(72 dollars)/(6 hr) = (x dollars)/(4 hr)`

Now we can cross-multiply:

72*4 = 6x

288 = 6x

x = 288/6 = $48

Answer 2

$48

Explanation:

Amount : hour

$72 : 6

$X : 4

4/6 = X/72

X = 72 × 4/6

X = 48
