over what range will the dealers cost vary?

Question

The markup over​ dealer's cost of a new car ranges from 11​% to 18​%.

If the sticker price is $11,000​, over what range will the​ dealer's cost​ vary?

Answer 1

Let x = dealer cost

If the markup is 11%, then x + 0.11x = 11000

1.11x = 11000

x = $9909.90

-------------------------------------------------------

If the markup is 18% , then x + 0.18x = 11000

1.18x = 11000

x = $9322.03

The range of the cost to the dealer is $9322.03 to $9909.90

Answer 2

89%-82%

11,000*.89=$9790

" *.82=$9020
