The total cost, c, in dollars to create calendars for a fundraiser can be found using the function c=5.5u+25 where u is the number of calendars made. If there are at least 10 calendars made, what is a possible domain for this function? A: 10≤x≤100

B: {-12, -11, 12, 20, 50}

C: {10, 11, 12, 13, 14}

D: 0≤x<50

The correct option is;

{10, 11, 12, 13. or 14}

Step-by-step explanation:

The given function for the total cost, c, to create calendars is c = 5.5u + 25

The domain of a function are the values of the input variables of the function with which the output (the values) of the function are found

Therefore, the domain of the given function are the values of the variable, u, in the function

Where;

u = The number of calendars made

∴ When u ≥ 10, we have;

The possible domain for the function are u = 10, 11, 12, 13. or 14...

Therefore, the correct option is {10, 11, 12, 13. or 14}
