Bill = 80 and divided by four and each get 20.

Now tip 15%(80) = 12 and even this divided by 4 and each get 3.

total 23.

Explanation

If four people shared the $80 bill equally, then each person paid for one-quarter of the bill, or \(\frac{80}{4}\)= $20.

The tip is calculated as a percent of the bill. Because the question asks about the amount that each (one) person paid, calculate the 15% tip based solely on one person’s portion of the bill ($20): (0.15) (20) = $3.

In total, each person paid $20 + $3 = $23.

Alternatively, find the total of the bill plus tip and take one-fourth of that for the total contribution of each person. The total of bill and tip is $80 + (0.15)($80) = $80 + $12 = $92. One-fourth of this is = $23.
