Chris's wages vary directly as the same time she works. if her wages for 20 hours are $150, what are her wages for 38 hours?

$285

Step-by-step explanation:

Since the wages vary directly with the time, then use a direct proportion.

$150 is to 20 hours as x is to 38 hours

150/20 = x/38

15/2 = x/38

2x = 15 * 38

x = 15 * 19

x = 285

the first one, all those points on the line just make a strait line.
