Use the information given below, to compare the cost of operating two different vehicles for one month (4 weeks). you are considering two different cars. you drive to work, a 20 mile round trip, five days a week. gasoline costs you $1.50 per gallon. car a gets 28 miles per gallon, would have $300 a year in maintenance costs, and would cost you $1,500 per year to insure. car b gets 19 miles per gallon, would have $500 a year in maintenance costs, and would cost you $1,000 per year to insure.

                                                   Car A                             Car B

Gas cost per month                   $21.429                            $31.579

insurance per month                  $125                                 $83.333

maintenance per month             $25                                 $41.667

Total cost per month                  $171.429                          $156.579

Step-by-step explanation:

we have to drive 20 mile round trip, for five days a week.

that means total number of days in a month we have to drive=5×4=20 days

hence total distance we have to drive in a moth=20×20 miles=400 miles.

Cost of gasoline=$ 1.50 per gallon.

now for Car A:

A gets 28 miles per gallon.

⇒ A has to pay $1.50 for 28 miles

that means the amount he has to pay for 1 mile=$

The amount he has to pay for 400 miles=$

                                                                  =$21.429

he has to pay $300 a year in maintenance cost.

A has to pay $25 per month in maintenance.

also he has to pay $1500 a year for insurance

i.e. A has to pay $125 per month for insurance.

Total cost per month=$ (21.429+25+125)

                                   =$171.429

for Car B:

B gets 19 miles per gallon.

⇒ B has to pay $1.50 for 19 miles.

that means the amount he has to pay for 1 mile=$

The amount he has to pay for 400 miles=$

                                                                    =31.579

he has to pay $500 a year in maintenance cost.

A has to pay $41.667 per month in maintenance.

also he has to pay $1000 a year for insurance

i.e. A has to pay $83.333 per month for insurance.

Total cost per month=$ (31.579+41.667+83.333)

                                  =$156.579

a² + b²= c²

24² + 7² = c²

c= 25

is there supposed to be a diagram or a graph for this one? ?
