Question

A salesperson earns $350 per week plus 10% of her weekly sales.
Find the sales necessary for the salesperson to earn at least $800 in
one week. Please help me understand and solve this.

Answer 1

let

x = dollar amount of sales done per week

and

y = total amount earned per week

Answer 2

If "A salesperson earns $350 per week plus 10% of her weekly sales", then the equation is

y = 350 + 0.10x

or

y = 0.10x + 350

Answer 3

we want to know the dollar amount of sales necessary (x) when y = 800 (when you earn $800 a week)

so plug in y = 800 and solve for x
