As a reward for being name employee of the year Janice will receive a 3.5 pay raise . If Janice new salary is 45,000 how much wa

satela [25.4K]

Answer:

Salary before pay raise = 43,478.26 (approx)

Step-by-step explanation:

Given that:

Janice new salary = 45,000

Pay raise = 3.5% = 0.035

Let the previous pay be x

Now according to given conditions:

0.035* x = 45,000 - x

Adding x on both sides we get:

0.035 x + x = 45,000 - x + x

1.035x = 45,000

Dividing both sides by 1.035 we get:

1.035/1.035 x = 45,000/1.035

x = 43,478.26

So, the salary before pay raise was 43,478 approx

proof:

Raise in salart = 3.5% of 43,478.26 = 1,521.74

New salary = old salary + raise in salary

New salary = 43,478.26 + 1,521.74

New salary = 45,000

Hence proved.

I hope it will help you!
