Question

You recently got a job a Dillards selling shoes. Each month you earn $450 plus one eigth of your sales. Whar amount in sales must you sell this month to earn more than $2000

Answer 1

let your amount of sales be x
let you total be y
y = 450 + x / 8
but you want y > 2000
2000 < 450 + x / 8
x / 8 > 1550
x > 1550 × 8
x > 12400
therefore you must sell at least $12,400
