Explanation:

Maria sells painting in a art gallery . she earns $ 375 each week plus a commission of 2.5 % of her sales. Her goal is to earn at least $500 .

The minimum amount of sales she must have this week to achieve her goal can be calculated as follows:

let a = sales

2.5% = 2.5/100 = 0.025

375 + 0.025(a) ≥ 500

0.025a ≥ 500 - 375

0.025a ≥ 125

divide both sides by 0.025

a ≥ 125/0.025

a ≥ 5000

She must at least sale $5000 worth of painting
