Brian buys 5 cookies and 1 bottle of water. The total cost is $8.75. If the bottle of water costs $1.25, which equation can be u
lubasha [3.4K]

Answer: $1.50/cookie

Step-by-step explanation:

Cookies = x

Water = y

5x + y = $8.75

y = 1.25

Plug in y-value into equation:

5x +1.25 = 8.75

5x = 8.75 - 1.25

5x = 7.50

x = 7.50/5

x = $1.50 for 1 cookie.
