Helen earns $7.50 an hour at her job, but if she works more than 35 hours in a week, she is paid 1 1/2 times her regular salary for the overtime hours worked. One week her gross pay was $307.50. How many overtime hours did she work that week?

Answers

7.50 * 35 = 262.50

307.50 - 262.50 = $45.00

7.50 * 1.5 = $11.25

45 / 11.25 = 4 OT hours

Answers

Answer:

  -1113

Step-by-step explanation:

You apparently want the sum of the 14-term arithmetic sequence ...

  -21, -30, -39, ..., -138

The average term is ...

  (-21 -138)/2 = -79.5

so the sum of the 14 terms is ...

  (14)(-79.5) = -1113

                                17

                                  Σ (15 – 9n)  = -1113

                                 η = 4

  • nth term

                         aₙ = 15 - 9n

        a₄ = 15-9*4 = 15-36= -21

       a₁₇ = 15 - 9(17) = -138

  • Sum;

                      S = (a₁ + aₙ)*n/2

         n = 14

         a₁ = a₄= -21

         aₙ = a₁₇ = -138

                   S = (-21 - 138)*14/2

                   S = -1113
