Algebra Linear Equation Question βͺ You are moving and need a rental truck. The rental company you have chosen charges a \$70/day fee plus \$0.20 for every mile you travel. Write a linear equation that expresses the total cost y, where x represents the number of miles you travel. Graph this equation. Then choose a number of miles, x, you travel that day and find the total cost of renting the truck. Solution 1. Step 1: Defining variables Let, πππ‘ππ πΆππ π‘ = π¦ and ππ. ππ πππππ  = π₯ 2. Step 2: Write the linear equation πππ‘ππ πππ π‘ = πΉππ₯ππ πππ π‘ + π£πππππππ πππ π‘ Here, fixed cost = daily rental cost = \$70 Variable cost = cost which depends on number of miles I am going to travel = Per mile cost x No of miles = π. πππ Thus, total cost (π) = π. πππ + ππ Solution 3. Step 3 We can see that π = π. πππ + ππ is a straight line, we need to find two points and connect them to draw the graph 4. Step 4 I will use π = π and πππ miles to draw the graph. 5. Step 5 Compute the two values of π¦ π€βππ π = π, ππ π = π. πππ + ππ = π. ππ π + ππ π = \$ππ π€βππ π = πππ, ππ π = π. ππ πππ + ππ = πππ + ππ π = \$πππ Graph π=π.π? ...
