One employee of a computer store is paid a base salary of MK21,500 a month plus an 8% commission on all sales over MK70,000 during the month. How much must the employee sell in 1 month to earn a total of MK31,700 for the month?

I think the total sales must equal $32000

Step-by-step explanation:

Given,

Base Salery = $2000

Commission = 8% in sales above 7000

To find out how much sales should be made so that the total earnings are $4000. Let the sales be x. Then the required linear equation is

2000 + 0.08 ( x - 7000) = 4000

2000 + 0.08x - 560 = 4000            (Using distributive property)

1440 + 0.08x = 4000                       (Simplifying)

0.08x = 2560                                  (Subtacting 1440 from both sides)

x = 2560/0.08                              (Dividing both sides by 0.08)

x = 32000

Thus, total sales must equal $32000

I hope this help you!
