There are 10 quarts of tea left from the party. Four students each drank 1.5 quarts of tea and 16 students each drank 2 quarts of tea. How many gallons of tea were at the beginning of the party?
4 students drank 1.5 quarts = 4 * 1.5 = <<4*1.5=6>>6 quarts
16 students drank 2 quarts = 16 * 2 = <<16*2=32>>32 quarts
Students drank 6 + 32 quarts = <<6+32=38>>38 quarts
Students + tea left = 38 + 10 quarts = <<38+10=48>>48 quarts
48 quarts = 12 gallons
The party started with 12 gallons of tea.
