Plug the coordinate pairs into the equation. The first value is the x, and the second value is why. Solve the equation and if the answer on both sides is the same number, the coordinate pair satisfied the equation
Answer:
More earn this summer per month = $30 more
Entire summer earning (for 2.5 months) = $1950
Step-by-step explanation:
For 2.5 months, you got 1875 dollars, so per month salary is:
1875/2.5 = $750 per month
This summer, you got a 4% raise, that means:
4% = 4/100 = 0.04
The raise is:
0.04 * 750 = $30 raise
So, new monthly salary is:
750 + 30 = $780
So, assuming you will work 2.5 months again this summer, you total earnings would be:
2.5 * 780 = $1950
