Question: #4 - Your restaurant bill comes to $24 before tip is added. If you want to include an 18% tip, how much will you add
#4 - Your restaurant bill comes to $24 before tip is added. If you want to include an 18% tip, how much will you add to the total?
y = the amount to be paid to the restaurant bill with the tip added.
x = the percentage
y = (x+1) x $24.00 solving for y I substitute the given value of x which is 18% to the equation
y = (1.18) x $24.00 multiply 1.18 x 24.00 giving me y
y = $28.32
Therefore, I can conclude that the restaurant bill with an 18% tip added will be $28.32
My question is, if I have only $28.00 on me, how can I calculate the percentage I would leave for a tip using this same equation as above?
