D: 85=1.26f

Step-by-step explanation

Step 1

Let

total = 85

tax = 6% = 0.6

tip= 20%= 0.20

tax + tip = 0.26* cost of the food

cost of the food = f

Step 2

make the equation

in words, then replace

the total cost = cost of food+ cost of tax and tip

replace


\begin{gathered} 85=f+0.26f \\ 85=f(1+0.26) \\ 85=1.26f \end{gathered}
