Brenda wants to create a formula for computing the total cost of any restaurant dinner bill that includes 6% sales tax, a 15% tip on the pre-tax amount, $5 for parking, and $2.50 for a coat check. Write a simplified expression that can be used to calculate the total cost of a dinner that costs d dollars before tax and tip are added. Simplify the expression.

unless if u could do my questions, if not i wouldn't want to

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
