In this question, we are asked to write an equation representing the total cost of renting a truck by Makayla.
We proceed as follows;
Form the question, we can deduce that there is an initial cost of $40 and a rental fee of $3 per mile driven.
Now, we were made to know that she had driven m miles. We now calculate the rental fee for this m miles she has driven. Mathematically, we only need to find the product here. The rental fees for the m Miles traveled would be m * 3 = $3m
Now the total cost C(m) would be = $40 + $3m or simply C(m) = $(40+3m)
