Question

Answer 1

Answer:

b. $2.50

Step-by-step 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
