First you cancel 7 and 28, and 3 and 9, so that leaves you with 4/3 x 15/17, then you cancel 3 and 15 so you get 4x5/17 which should give you 20/17!

Answer:

C

Step-by-step explanation:

ok so, assuming that b cannot equal 0, we can divide it on both sides

(3a - 5)/c = b/b

anything divided by itself is 1

(3a - 5)/c = 1

multiply c:

3a - 5 = c

3a = c + 5

a = (c + 5)/3

You set up a hot chocolate stand out of football game the cost of your supplies and $75 you charge $.50 for each cup of hot choc

Elodia [21]

P = .50c - 75

You need work your cost into your total profit, $75, which was spent. Since that money was lost, we can say it is -$75. You make 50¢ per cup of hot choclate, which is $0.50. Putting that all together, you can make the function P = .50c - 75.
