David opened a coffee shop and sold 60 mochas the first day at $2 per cup. he wants to increase the price per cup to increase his revenue. he found out that for every $0.25 increase, x, in the price per cup, the number of cups he sold decreased by 2 per day. how can david find the equation which represents his daily revenue, in dollars, from mocha sales when the price is increased x times?

Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120

We know that David wants to increase the price per cup to increase his revenue. He found out that for every $0.25 grows( increase), x, in the price for each cup.

In the event of a price increase, 2 cups remain unsold, and doubling the cups is still not sold. Then the numbers are sold (60-2x). Depending on the choice:

Revenue= (60 -2x)(2 +0.25x)

60·2 +60·0.25x -2x·2 -2x·0.25x

= -0.5x² +11x +120

24+x=y
