Answer:
17b = w
Explanation:
17 times the number of bottles = the number of ounces of water
Then you just plug in the numbers you are given
17(51) = w
17 x 51 = 867
51 bottles of water holds 867 ounces
17b = (51)
divide both sides by 17
51/17 = 3
b = 3
It would take 3 bottles of water to hold 51 ounces
