Linear Equation

Question
▪ 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
❑ Define 𝒚 and 𝒙
❑ 𝑻𝒐𝒕𝒂𝒍𝑪𝒐𝒔𝒕 = 𝒚
❑𝑵𝒐. 𝒐𝒇 𝒎𝒊𝒍𝒆𝒔 = 𝒙

2. Step 2
❑ Write the linear equation
𝒚 = 𝟎. 𝟐𝟎𝒙 + 𝟕𝟎

3. Step 3
From our equation we can see that 𝒙 is a straight li...
