Hello! Here to help with Science, Math, ACT/SAT prep
Equation 1: Total = tip + amount
Equation 2: tip = 0.2 X amount
Solve for the amount using the second equation and then plug in the values to find the total bill using the first equation.

Yes of course! So the first step is to find the cost of the food. You do this by using the information you know about the tip. Since tip is calculated using the equation tip = tip%*food_cost, we use the information we have to get 35.21=0.2*food_cost and then we solve for food_cost. We use the result and add the tip to get the total bill. So Total Bill = food_cost + 35.21. Hope this helps!
