Answer:
(a) $6550
(b) $1511.54
Step-by-step explanation:
(a) You can solve the equation
... 12 × (monthly salary) = $78,600
by dividing both sides of the equation by 12.
... (monthly salary) = $78,600/12 = $6,550
(b) You know there are 52 weeks in a year, so you know that ...
... 52 × (weekly salary) = $78,600
... (weekly salary) = $78,600/52 ≈ $1,511.54 . . . . . . . divide by 52
