d. Clare wrote the equation y = 36 - 1, with * representing the amount of grape juice used, in
ounces, and Y representing the amount of sparkling water used, in ounces. Explain why Clare's equation matches the story.

e. Kiran wrote the equation I = y/ + 36, with * representing the amount of grape juice used, in
