To determine the maximum number of bags of popcorn Madeline can buy, we need to calculate the number of full bags she can afford.

Step 1: Calculate the cost of two bottles of water.
The cost of one bottle of mineral water is $2.75.
Therefore, the total cost of two bottles is 2 * $2.75 = $5.50.

Step 2: Subtract the cost of the water bottles from Madeline's total amount.
Madeline has $18, and she spent $5.50 on water bottles.
So, she now has $18 - $5.50 = $12.50 remaining.

Step 3: Find out how many bags of popcorn Madeline can afford with the remaining amount.
The cost of one bag of popcorn is $3.50.
To calculate the maximum number of bags, we divide the remaining amount ($12.50) by the cost of one bag ($3.50):
$12.50 ÷ $3.50 ≈ 3.57.

Since Madeline can't buy a fraction of a bag, she can buy a maximum of 3 bags of popcorn.

Therefore, Madeline can buy at most 3 bags of popcorn.

18.00> 2*2.75 + N*3.50

subtract 5.50 from each side (the water)
15.50>N*3.50
divide each side by 3.50
4.4>N
so N cannot be greater than 4.
