Answer:
A) Her salary after the raise is $1560 /month
B) 4% a month
Explanation:
(a)
A woman was making salary / month = $1500
Reduced % in salary = 20%
Reduced amount in salary/month = $1500 x 20% = $300 /month
Salary after reduced amount = $1500 - $300 = $1200 /month
A year later after a dramatic improvement in sales, increment % in salary
= 30% over reduced salary
= 1200 x (30/100) ==> $360 /month
Salary after increment = $1200 + $360 ==> $1560 /month
∴ the salary after raise is $1560 /month
(b)
starting salary = $1500 /month
Salary increment = $1560 - $1500 =$60 /month
%change = (Salary Increment / starting salary) x 100
= (60/1500) x 100
= 4% a month
