Maria sells paintings in an art gallery. she earns $375 each week plus a commission equal to 2.5% of her sales. this week her is goal is to earn at least $500. what is the minimum amount of sales she must have this week to achieve her goal?

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

She must at least sale $5000 worth of painting

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
