PLZ HELP
Lakita has 65 water bottles for the 5K race participants. In addition, she is considering buying boxes of water bottles that have 16 water bottles each. All of the boxes cost the same. Lakita can buy up to 5 boxes of water bottles given the amount of money she has. Let x represents the number of boxes of water bottles Lakita buys. Write a function rule to describe how many water bottles Lakita will have based on the number of boxes she buys. Find a reasonable range for the function.
A - f(x) = 65x + 16
{145}
B - f(x) = 16x + 65
{65, 81, 97, 113, 129, 145}
C - f(x) = 65x + 16
{81, 97, 113, 129, 145}
D - f(x) = 16x + 65
{65, 81, 97, 113, 129}

she has 65 water bottles....and she is buying boxes of water bottles (x) that hold 16 water bottles each. She can only buy up to 5 water bottles.

f(x) = 16x + 65...where f(x) = total water bottles and x = number of boxes
x < = 5.....here is ur restriction

the range is ur f(x) values which represent the total number of water bottles...keep in mind, she can only buy 5. Therefore, the numbers that can be subbing in for x are 0 thru 5.

So when subbing in 0 thru 5 for x, the results for f(x) are :
{ 65,81,97,113,129 } <== ur range
