They can buy 6 workbooks with $90. To find the unit rate we simply divide the cost ($60) by the number of books (4). That gives us $15, the cost of 1 workbook. So now to find out how many workbooks can be purchased with $90, we divide 90 by 15. That’s how I got 6 workbooks. Hope this helps.

Answer:
Step-by-step explanation:
A. Price is 1.75
Total revenue, if number of galsses equals X is 1.75X
Total cost function of X glasses of lemonade is 25+0.1X
Profit function is Revenue - Cost, P=1.75X-25-0.1X=1.65X-25
C. Marginal profit= d/dx(1.65x-25) = 1.65-0=1.65
X=300 glasses, P'(300)=1.65
X=700 glasses, P'(700)=1.65
