Answer:
cost when 400 miles is driven is $143.
Step-by-step explanation:
Model for cost calculation: C=0.32m + 15
We have to find cost when no. of miles driven is 400.
To find that cost we need to plug 400 in place of m.
C=0.32m + 15
=> c = 0.32*400 + 15
=> c = 128 + 15 = 143
Thus, cost when 400 miles is driven is $143.
The simplest form is 3/8. this because 4 divides both sides
