Question

Simplify each expression and identify the units you and two friends all have the same real meal for lunch.Each meal costs c dollars plus a tax of 6% of the cost and a tip of 20% of the cost. You use a $10 gift certificate. You can represent the total cost with the expression 3c+(0.06+0.20)(3c)-10

Answer 1

T.C = 3c+(0.06+0.20)(3c)-10
3c = cost of 3 meals
3c(0.06 + 0.20) = tax and tip expenses
10 = value of gift certificate
T.C = 3c + 0.26*3c - 10 = 3.78c - 10.
