Answer 1

b. $2.50

Explanation:

Let us take a step by step approach by simplifying each sentence:

Sentence 1: Hector works 12 hours per week at a part-time hours per week at a part-time job

Number of hours worked per week = 12hours

Sentence 2: His original pay rate was $8.00 per hour. but he recently received a raise of x dollars per hour

Pay per hour is 8hr, a raise of x gives 8 + x

Sentence 3: New total wage = 12(8+x)

Sentence 4: Amount earned last week = $126

New total wage = Amount earned last week

12(8 + x ) = 126

96 + 12x = 126

12x = 126 - 96

12x = 30

x = $2.50

Amount of raise is $2.50
