Dani is making punch for a family picnic. She adds 16 fluid ounces of orange juice, 16 fluid ounces of lemon juice, and 8 fluid ounces of lime juice to 64 fluid ounces of water. How many 8-ounce glasses of punch can she fill?

$16 + 16 + 8 + 64 = 2 \left(8\right) + 2 \left(8\right) + 8 + 8 \left(8\right) = 13 \left(8\right)$
