Angle 1 is 107 degree, and the other one is 73 degrees (180-107=73)
2 gallons * $2.58 per gallon = $5.16 expenses (total spent)
2 gallons * 16 cups = 32 total servings
32 cups * $0.75 per cup = $24 gross revenue (total income)
$24 - $5.16 = $19.84 net revenue (profit)
Then, the median is found by taking the mean (or average) of the two middle most numbers.
