Answer:
a. Letting m represent the number of additional miles driven, we have .35m.
b. Devon paid $43 for additional mileage.
Step-by-step explanation:
For part b: $421 - ($54 × 7)
= $421 - $378 = $43
The algebraic expression to represent the amount Devon paid for additional mileage only is 0.35m and Devon pays for additional mileage if he paid a total of $421 for the rental car is $43.
What is linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
During a long weekend, Devon paid a total of x dollars for a rental car so he could visit his family. He rented the car for 7 days at a rate of $54 per day.
For part (a):
Write an algebraic expression to represent the amount Devon paid for additional mileage only.
The amount Devon paid for additional mileage only = 0.35m
For part (b):
Devon pays for additional mileage if he paid a total of $421 for the car rental is:
= $421 - ($54 × 7)
= $43
Thus, the algebraic expression to represent the amount Devon paid for additional mileage only is 0.35m and Devon pays for additional mileage if he paid a total of $421 for the rental car is $43.
