Denise works 12 hours per week at a part-time job. Her original pay rate was $8.00 per hour, but she recently received a raise of x dollars per hour. Her new total weekely pay, y, is represented by the equation: y = 12(8+x). If Denise earned $126 last week, what was the amount of Denise's raise per hour?

$2.5

Step-by-step explanation:

Given:

Hours worked per week = 12

Original pay = $8 per hour

Increase in pay = $x per hour

y = 12(8+x)

Where,

y = total weekly pay

If Denise earned $126 last week, what was the amount of Denise's raise per hour?

y = 12(8+x)

126 = 12 (8 + x)

126 = 96 + 12x

126 - 96 = 12x

30 = 12x

Divide both sides by 12

x = 30 / 12

= 2.5

x = $2.5

The amount of Denise's raise per hour is $2.5

the answer is c. 23/3
