Answer:
Step-by-step explanation:
Let's assume this is a function
<u>The points are</u>
<u>Since it is linear relation, we'll get the slope intercept form</u>
- g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept
<u>Using the points, let's calculate the formula</u>
- m = (10 - 13)/(60 - 40) = -3/20
- 10 = -3/20*60 + b
- 10 = - 9 + b
- b = 19
<u>So the formula is:</u>
Unpaid balance 283.63-60=223.63
Finance charge
223.63*(0.015/12)=3.35
New balance
223.63+3.35+51.36==278.34
You times the numerator by the numerator and the denominator by the denominator
thats all
