10. Chris Evans drives 300 miles per week in his Honda Civic that gets 22 miles per gallon of gas. He is considering buying a new fuel-efficient car for $20,000 (after trade-in of your Honda Civic)
that gets 50 miles per gallon. Insurance premiums for the new car and old care are $900 and
$500 per year respectively. If he decides to keep his car, he will need to spend $1200 on repairs
per year. Assume gas costs $3.50 per gallon over a 5-year period.
what is the cost of the old car?
a.
b. what is the cost of the new car?

There are 52 weeks in a year

Total of 5 years

Step-by-step explanation:

Per Week the Miles are 300 miles

Total Miles over the course of 5 years = Miles per Week * Number of Weeks in a Year * Number of Years

How did i solve this:

Total Cost of New Car = Total Cost of Gas + Total Insurance Premium + Purchase Price of New Car = 5460 + 4500 + 20,000 = $29,960  

Total Cost of New Car = $29,960

= 300 * 52 * 5 = 78,000 miles in 5 years

Hope this helps.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
