To fill 50 12-fl oz cups, you need 50 * 12 fl oz = 600 fl oz
There are 128 fl oz in a gallon
600/128 = 4.6875
600 fl oz = 4.6875 gallons
600 fl oz is under 5 gallons, so 5 gallons is enough.
1 qt = 32 fl oz
17 qt = 17 * 32 fl oz = 544 fl oz
17 quarts is 544 fl oz, which is under the needed 600 fl oz, so 17 quarts is not enough.
Answer: 5 gallons
S= savings before she bought the dress s - $55 would be her new balance after she bought the dress.
We could also talk about her savings now (after her purchase). If we let n=now
n + $55 would be her balance before she bought the dress.
Well this only simplifies to a smaller equation
so the answer would be...
2a²-9b²
Substituting m for 9
h(9) = 9^2 - 3*9
h(9) = 81 -27
h(9) = 54
Third option!
