uestion 11 (2poins) ian Lee researched the dealer's cost of a new car he wanted to purchase. He found that the dealer's ase cost was \( \$ 23,450.50 \) and the dealer's cost for the options he wanted was \( \$ 2,300.75 \). The dealer ould pass the \( \$ 650 \) destination charge on to the consumer. If the percent of dealer's cost is \( 84 \% \) nd the percent of dealer's cost of options is \( 88 \% \), find the car's sticker price.
