Answer:
5.75x = f(x)
22.99 + 2.09x = g(x)
Step-by-step explanation:
Divide them into two parts:
Normal drinks and commemorative drinks
- With normal, only $5.75 is related (Only one drink at a time so 5.75x)
- With commemorative, $22.99 and $2.09 are related (A one time fee of $22.99, then a refill of $2.09; so 22.99 + 2.09x)
