This is how much they will tip.
Add this to the original bill;
5^2 is 25 and 25x6 is 150sq ft
8(p-2) = 32

+16 on each side
8p= 48
Divide by 8 on each side
P= 6
Answer:
20, 60, 15
Step-by-step explanation:
Let the third number be n, then
The first number is n + 5 and the second number is 4n
Sum the 3 numbers and equate to 95, that is
n + 5 + 4n + n = 95 ← collect like terms on left side
6n + 5 = 95 ( subtract 5 from both sides )
6n = 90 ( divide both sides by 6 )
n = 15
Thus
The first number is 15 + 5 = 20
The second number is 4 × 15 = 60
The third number is 15
