Question

PLEASE HELP :)

Mrs. Bell's class is selling Hobbs Middle Jaguar t-shirts to raise money for a trip. They typically sell 400 t-shirts a year for $10 per shirt. Mrs bell knows that for every $1 increase in price, they will sell 20 less t-shirts. What is the revenue function R(x), where x represents the $1 price increases and revenue is equal the number of t-shirts sold times the cost of each shirt

Answer 1

I'll be back to answer your question.

1 x 10 - 400 = 2x
380 = 2x
388 / 2 = 2x / 2
388 / 2 = x
194 = x
