Question

Sandy's monthly earnings consist of a fixed salary of $2,500 and a 10% commission on all her monthly sales. To cover her planned expenses, Sandy needs to earn an income of at least $6,000 this month. Write and solve an algebraic inequality to find the amount of sales Sandy needs to cover her planned expenses.

Answer 1

$35,000

Explanation:

Given data

Fixed salary= $2,500

Commission= 10%

Sandy wants to earn $6,000 this month

Let the total earning be y and the sales be x

Therefore the expression for Sandy's earning is given as

y=2500+0.1x---------------1

when y= $6,000

substitute in 1 and solve for x

6000=2500+0.1x

6000-2500=0.1x

3500=0.1x

x= 3500/0.1

x= $35,000

Hence the amount of sales will be $35,000
