Y and x are not constants, so you don’t have to find the value of them.
On the other hand, you do have to find m and b. M is the slope and B is where the y-axis is crossed, or what her balance was at week 0.
To find slope: (y1-y2)/(x1-x2) or the rise over run.
130-280= -150
2-8= -6
-150/-6= 25= m
This means she adds $25 each week.
To find the y-intercept: this is where x=0 and y is some unknown value. We are given the amount at the end of 2 weeks, so we just need to go back 2 weeks. She adds $25 each week. -2 weeks • 25 = -$50
130-50= 80 = b, or the initial amount in the account.
We need to plug b and m into the equation.
y=25x+80
Answer:
Your new monthly salary would be $1,457.50.
Step-by-step explanation:
You previously received a monthly salary of $1,375.00
Now by economy expansion, causing wages to increase by = 6%
Increment of the salary = 6% of 1,375.00
= 
× 1,375
= 0.06 × 1,375 = $82.50
So your new monthly salary would be = $1,375.00 + $82.50 = $1,457.50
Answer:
240
Step-by-step explanation:
So 60/100 x (n) = 144
We should be able to multiple both sides by 100, and divide each side by 60 to get our answer.
n = 144 x (100/60) which then equals 240.
