The car-driven cost increases with an increase in miles. After substituting x = 1,2,3,4.... you will find that it is increasing by 0.29 every time.
What is an equation?
Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right is shown to be equal in reference to one another.
According to the question,
y = 0.29 x + 209
Where x is the number of miles and y is representing the driving cost of the car.
Substitute x = 1,2,3,4...... in the above equation.
y₁ = 0.29 (1) + 209 = 209.29
y₂ = 0.29 (2) + 209 = 209.58
y₃ = 0.29 (3) + 209 = 209.87
y₄ = 0.29 (4) + 209 = 210.16 and so on.
Now, take the difference,
y₂ - y₁ = 0.29
y₃ - y₂ = 0.29
y₄ - y₃ = 0.29
Hence, it is clear that with an increase in each mile the cost is increasing by 0.29.
