Good morning Sir/Ma'am!
Answer:
f(r) = 40r + 26
If she can only afford 10 rolls, then the maximum number of nickels Cindy will have is:
f(10) = 40(10) + 26 = 426 nickels
Step-by-step explanation:
Given function f(r)=40r+26, where r is the number of rolls of nickels she gets.
as it is already mentioned that she can get up to 10 rolls of nickels.
Therefore domain of function contains r ≤10,such that r is a natural number.
i.e.Domain of f(r)=all integers from 1 to 10, inclusive.
Domain of a f(x) is a set of values of x which make function f(x) well defined.

Have a great day! ( :
Set the two values equal to each other with 18x-2=12x+2 and then plug it in to the equation and solve
1 gallon = 128 ounces
Divide total ounces by ounces per cup:
128 / 4 = 32
She had 32 servings
