U2.L7.HW: Linear Inequalities: Question 28

Question

What equation do I need to put together to solve the following problem:

A local salesman receives a base salary of $750 monthly. He also receives a commission of 7% on all sales over $1050. How much would he have to sell in a month if he needed to have a monthly income of $1600? 

He would need to sell $ (answer here) to reach his needed monthly income needs. (Round answer to the nearest penny. Do not use commas!)

Answer 1

1600 = 750 + 850

850 = .07S

S =850/.07

= about $12,142.86 over $1,050

sales are needed of 12,142.86+1,050

= $13,192.86
