In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6

We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1

Both solutions meet the condition.

torisob [31]

Answer:

Total sales= 10000

Step-by-step explanation:

Given data

monthly salary=$1500

commission on total sales= 5.75%

gross pay=$2,075

Firstly, let us deduct the salary

2075-1500=$575

so Saiah earned a commission of $575

let the total sales be x

so 5.75% of x= $575

5.75/100*x=576

0.0575x=575

x=575/0.0575

x=10000 sales
