Answer B is correct --> y = 3.50x + 45
y represents the total cost
x represents the number of miles towed (since it costs 3.50 per one mile, that's why the variable x needs to be here because we don't know how many miles we'll have yet)
Answer:
$1.6
Step-by-step explanation:
The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost
Using the concept of cross multiplication we say that if
1.45 is equivalent to $2.32
1 is equivalent to x

Therefore, the company incurs $1.6 for each plug
