<span>1.255 times the party bill.
x = party bill
s = sales tax
t = tip
C = total cost = the bill, plus the sales tax, and the tip
C = x + s + t
We know that both the sales tax and the tip are percentages based on the party bill. The sales tax is equal to 7.5% of the party bill. The tip is equal to 18% of the party bill.
so,
s = (0.075)*x
and,
t = (0.18)*x
Then we replace the s and the t in our equation,
C = x + 0.075x + 0.18x
Then, we add the elements together.
C = (1+0.075+0.18)x
C = 1.255x</span>

Step-by-step explanation:
If they each kept the same amount of the $50 prize, then we divide $50
by 2 people, giving each of them $25 winnings. Your question is then a
little confusing because it could be answered in two ways. Did they
each keep $20.75 out of their $25 winnings, or did the two of them keep
$20.75 in a combined total? Please read your question again to see
which might be the case. I'm answering on the assumption that they each
kept $20.75.
STEP 1:
divide total prize money by 2
= $50 ÷ 2
= $25 each won
STEP 2:
If they each kept $20.75
= $25 won - $20.75 each kept
= $4.25 each gave away
STEP 3:
multiply amount given away by 2 people
= $4.25 * 2 people
= $8.50 total given away
ANSWER: The total given to Romy is $8.50.
Hope this helps! :)
