Pam sells racing team caps at her concession stand at an automobile race track. She has 100 of last year's caps and 300 of this year's caps in stock. Pam knows from past experience that her customers will pay $7 more for this year's cap than for last year's. She has calculated that she needs to make $5300 in sales of caps. Assuming that she will sell all of the caps, how much should Pam charge for each type of cap?
