Stan took Lily to his friends restaurant on a date. The friend told the waiter to remove the $12 dessert from Stan's bill. Stan tipped the waiter 20 % which was a $15 tip. Fill in the blanks to write an equation that will determine the amount of the original bill,b.

Answer 1

The original bill, b, can be determined by adding the cost of the dessert, x, to the amount tipped to the waiter, t:

b = x + t

According to the given information, the cost of the dessert is $12 and the tip amount is $15:

b = $12 + $15

Now we can evaluate the expression to find the value of b:

b = $27
