Mandy’s monthly earnings consist of a fixed salary of $2800 and an 18% commission on all her monthly sales. To cover her planned expenses, Mandy needs to earn an income of at least $6400 this month.

Part A: Write an inequality that, when solved, will give the amount of sales Mandy needs to cover her planned expenses.

Part B: Solve the inequality to state the amount of sales Mandy needs to cover her expenses.

(HINT: Write it as an equation first, and then change the = sign to an inequality sign ≥)

Sagot :

2800 + 1.18x = y
x = monthly sales
y = monthly income
y needs to be at least 6400 so that means;

2800 + 1.18x ≥  6400
1.18x ≥ 6400 - 2800
x ≥ (6400 -2800) / 1.18
x ≥ 3050

So she needs to earn at least 3050, which means ≥ 3050
