Thus, a product that normally costs $20 with a 75 percent discount will cost you $5.00, and you saved $15.00. You can also calculate how much you save by simply moving the period in 75.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x .75 = $15.00 savings.
You should be able to find the maximum value of c by simply substituting the maximum values for x and y.
So we'll let x = -2 and y = 6.
The equation is is now as follows:
c = 5(-2) + 4(6)
c = -10 + 24
c = 14
Therefore the maximum value for c is 14.

1.93x3=5.79 but were not done because you need to add tax. So simply multiply 5.79 by 0.5 which equals .2895 round to the nearest cent so .29 then add .29 to 5.79 6.08.
The .05 is the tax % because you always have to remember that a tax % out of 100 is . then whatever % if it's a single number like 1 or 2 then it's like.01 or .02 hen multiply by the full amount. But that isn't the final answer because that is the tax amount. So add it back to the full number. That's how I found the answer.
The answer is 6.08
30(30 – x) = 540
distribute
900 -30x = 540
subtract 900 from each side
-30x = -360
divide by -30
x =12
