Question 221875: I just want to know if I am solving the problems right.
1) Solve each of the following for the requested variable:
a) P=2L+2W for L
P-2W=2L+2W-2W
P-2W=2L/2
P-2W/2=L
b)(3x+Y)/2=2 for y

Question 222654: For the Fall Harvest Festival your Math club decides to sell apple cider. You can get a good deal on bulk apple cider by buying 30 gallons for $90. At the club meeting, one member suggests buying the apple cider from her uncle, who has a nearby organic apple orchard. He will lower his price for the club to $5 per gallon. You find that you can only get paper cups in batches of 100 at $2 per 100.
If you want to sell all 30 gallons in 8-ounce cups, how many cups will you need to buy? (Note: 1 gallon= 4 quarts and 1 quart= 32 ounces).
