Step-by-step explanation:
This follows the equation y=4x+18
We would replace x with the week number and solve.
4(4)+18
16+18

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
It looks like the scale is balanced so that means you can set one side equal to the other which leaves you with the equation x+(-10)=-16
To get x by itself add x to each side to get x=-6
X=-6 is your answer
Well, we can substitute the variables and get :
9(21)+3(3)(21)+12
Then we simplify :
189+189+12
To get :
390 flowers
By the way you might be confused like I was for it said "a cake topping," whilst I assumed all tables had cake toppings which is untrue and I nearly ended up with 630 flowers.
