5y+8
When you figure out what y is you plug it in and do PEMDAS.
But if it doesn't tell you what y is then the equation I wrote is the answer.
So 15/3 = 5 then
vinegar = 5x2 = 10 cups
water = 5x1 = 5 cups
Answer:
999
Step-by-step explanation:

The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,
y = (25 - x)(100 + 5x)
Simplifying,
y = 2500 + 25x - 5x²
We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.
dy/dx = 0 = 25 - 10x
The value of x is 2.5.
The price of the cake should be 25 - 2.5 = 22.5.
Thus, the price of the cake that will give the maximum potential revenue is $22.5.
Answer is 78.54, when rounding the decimals is becomes 78.50
