A senior employee who works 16 hours earns $39.50 more than a junior employee who works 18 hours. The senior employee earns $14 per hour. What is the hourly pay for the junior employee in dollars and cents? (IN A TEST)

hourly pay for the junior employee in dollars and cents=$10.25

Step-by-step explanation:

Step 1

Total amount  senior employee is being paid = amount per hour x hours worked

 = $14 × 16 = $224.00

 Total amount of junior employee  since he/ she collects $39.50 less than senior employee= $224.00 - $39.50

                             = $184.50

Step 2

hourly pay of junior colleague= Total pay of junior colleague/ Hours worked

 =$184.50 / 18 hours

 = $10.25 per hour

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
