Answer:
She must at least sale $5000 worth of painting
Step-by-step 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
im not 100% sure but i think its 9.375
Passed Percentage= (9/20) * 100 = 9 * 5 = 45%
200 ; 2^3 x 5^2
