The function y = 3.75 + 2.50(x - 3) can be used to determine the cost in dollars for a uber ride of x miles. What is the rate of
change of the cost in dollars with respect to the number of miles? PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER. Multiple choices:
A. $3.75 per mile
B. $6.25 per mile
C. $4.75 per mile
D. $2.50 per mile
Differentiate y with respect to x dy/dx= d/dx(<span>3.75 + 2.50(x - 3)) </span> <span /><span /><span>dy/dx= 0+2.5(1) - 0=2.5 </span> <span /><span /><span>Hence, from the above calculations it is proven that the rate of change of the cost in dollars </span><span> </span><span>=dy/dx </span><span> </span><span>=2.5</span>
