You have $10.00 to spend on a birthday gift. So you go to the dollar store where each item costs exactly $1.25. You also have to pay $1.25 no matter how many items that you purchase. Let the
number of items be represented by the variable n. What is the cost function?
a. cost = $1.25 xn
b. cost = $1.25 X n + $1.25
c. cost = $10.00 - ($1.5 x n + $1.25)
d. cost = $10.00+ ($1.25 X n + $1.25)
