Problema Solution

The markup over dealer's cost of a new car ranges from 10% to 24%. If the sticker price is 29,000, over what range will the dealer's cost vary?

Answer provided by our tutors

Let

Cost = c (by cost we mean dealer cost)

Markup = Sale price − Cost

Sale price = $290,000

Markup = 290,000 - c

Markup = 10% of Cost that is

Markup = 10% of c

Markup = 0.10c

No we have the following equation:

0.10c = 290,000 - c

c = $263,636.364

The dealers cost for 10% markup is $263,636.364.

Fir Markup = 24% of Cost we have Markup = 0.24c:

0.24c = 290,000 - c

c = $233,870.968

The dealers cost will vary in the interval [$233,870.968, $263,636.364].
