First week: 40 hours
Total Earning = 40 x $10.20 + (40 - 35) x $1.30 = $414.50
Second Week: 38 hours
Total Earning = 40 x $10.20 + (40 - 38) x $1.30 = $410.60
Total for the two weeks = $414.50 + $410.60 = $825.10
Answer: $825.10

Answer:
y = 5/2x + 5
Step-by-step explanation:
Find slope: (0 - 5) / (-2 - 0) = 5/2; m = 5/2
Find y intercept: 5 = 5/2x + b --) 5 = 5/2(0) + b --) b = 5
Answer:
5 weeks.
Step-by-step explanation:
We have $60, and we're saving an additional $5 each week:
![60+5w](https://tex.z-dn.net/?f=60%2B5w)
Our brother has $45, and is saving an additional $8 each week:
![45+8w](https://tex.z-dn.net/?f=45%2B8w)
Let's set up an equation:
![60+5w=45+8w](https://tex.z-dn.net/?f=60%2B5w%3D45%2B8w)
We had to set these two expressions equal to each other because our end result should be equal.
Subtract
from both sides of the equation:
![5w=-15+8w](https://tex.z-dn.net/?f=5w%3D-15%2B8w)
Subtract
from both sides of the equation:
![-3w=-15](https://tex.z-dn.net/?f=-3w%3D-15)
Divide by the coefficient of
, which is
:
![w=5](https://tex.z-dn.net/?f=w%3D5)
Check your work:
You can check your work with substitution. Take the initial equation and substitute
with
:
![60+5(5)=45+8(5)](https://tex.z-dn.net/?f=60%2B5%285%29%3D45%2B8%285%29)
Simplify:
It checks out!
