Question

A gas station sells a coffee mug filled with coffee for $3. For each refill, using the same mug, the gas station charges $1.25 for the coffee. If y represents the total cost and x represents the total number of filled coffee mugs purchased, which function rule describes this pattern?

A y = 1.25 (x+1) +3
B y = 1.25 (x+1) +3
C y = 3 + 1.25x
D y = 3 (x-1) - 1 .25

Answer 1

the answer is c) y = 3+ 1.25x

Explanation:

it c because per cup is $3 and each refill is 1.25 and x is because we dont know who many refills he going to get so it is 3+1.25x

Answer 2

Answer: y = 3 + 1.25x

y = 3 + 1.25x

With the constant term 3 representing mug filled with coffee for $3.

And the variable term which is 1.25x being charges any number of refill made
