88/108 *100 = 81.48
100-81.48 = 18.52
I have heard this question before
45 is the whole number.
9 is the tenth number
7 is the hundredth number.
2 is the thousandth number.
So, its only one hundredth number in this problem
2 gallons * $2.58 per gallon = $5.16 expenses (total spent)
2 gallons * 16 cups = 32 total servings
32 cups * $0.75 per cup = $24 gross revenue (total income)
$24 - $5.16 = $19.84 net revenue (profit)
To find r, first write out the equation:

Next, multiply both sides by 2:

Now, subtract both sides by 4:

Divide both sides by 3:

The answer to this problem is
r = 2. Hope this helps and have a phenomenal day!
