Bradley works as a traveling salesman and leases a car for his business. the leasing company has a base rate for the first 15,000 miles per year, but has an additional charge of $500 + $0.25/mile for each mile over the 15,000. bradley has already driven 4300 miles in the first three months. if he drives a similar amount for the rest of the year, how much will he have to pay extra? show all work and explain your answer.

Bradley has to pay $1050 extra to the leasing company.

Step-by-step explanation:

Distance traveled by Bradley's car in 3 months i.e.1/4 of year =4300 miles

Distance traveled by Bradley's car in 1 year(12 months) =4 times he drove for 1/4 of year=4×4300=17200 miles

Now,Extra distance covered by car=17200-15000=2200 miles

As there is a additional charge of $500 + $0.25/mile for each mile over the 15,000.

Thus, he has to pay extra amount=$500+$0.25 times extra distance=$500+$(0.25×2200)=$500+$550=$1050

∴ Bradley has to pay $1050 extra to the leasing company.

he answer is x=1x3 because x=1 to x=3
