Step-by-step explanation:
40-4.5*8=4
leaving 4 dollars to spend on 4 drinks
6x + 4 - x = 2(x+1)
First combine like terms on the left side:
6x-x - 5x
So you have 5x+4 on the left side.
Then use the distributive property on the right side:
2(x+1) becomes 2x +2
Now you have 5x +4 = 2x +2
Subtract 4 from each side:
5x = 2x -2
Subtract 2x from each side:
3x = -2
Divide both sides by 3:
x = -2/3
The equation for the first part would be 4.50p+40=112.
This is because he earns 40 dollars in wages which doesn't change but the number of shoes he commissions, which would be 4.50 per pair. varies based on how many he commissions.
The answer to your second part would be 16.
To find the number, you subtract 40 from each side which gets you 4.50 = 72. From there you just divide which gets you 16.
Another easy way to do it would just be substituting until you find the right number like on a calculator but if you don't have a calculator on hand (let's say for a test), than the first way would be more effective.
Answer:
The graph (or piecewise function) shows that for a profit of $1,000 the salesperson will earn a commission of 17%:
C(p) = 0.17 p
C(1,000) = 0.17 (1,000)
C(1,000) = 170
Therefore, the salesperson will earn $170 as commission on a profit of $1,000.
If the car sells for a profit of $1,500, the commission will still be 17%. This commission is governed by the second equation because the third equation (21%) does not include the endpoint 1,500. So:
C(p) = 0.17 p
C(1,500) = 0.17 (1,500)
C(1,500) = 255
The salesperson will earn $255 as commission on a profit of $1,500.
