Andres works 20 hours per week at a part-time job. His original pay rate was $10.00 per hour, but he recently received a pay raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y=20(10+x).

If Andres earned $210 last week, what was the amount of Andres' raise per hour?

Answer: $0.5

Step-by-step explanation:

Pay for week = 20h × $10

$200

Raise = x

New weekly pay = y = 20 (10+x)

Last week = $210

$210 = 20 (10+x)

$210 ÷ 20 = 10+ x

10.5-10 = x

$0.5 = x

Answer:

50 cents / hour.

Explanation:

y=20(10+x)

210 = 20(10 + x)

210 = 200 + 20x

20x = 10

x = 0.5.
