You do 40 x 10 sinse it says that it is 40 pints per box and it will = 400
1) Plug in 2 into the equation:
f(x) = 2x - 6
2) f(2) = 2(2) - 6
f(2) = 4 - 6
f(2) = -2
Feel free to ask if you need me to clarify anything! :)
3000:100×6=180 liters
180×1,2=216 $
216÷6=36$/friend
x - 12/6 = 9
x - 1/2 = 9
x = 9 + 1/2
x = (9/1)×2 + 1/2
x = 18/2 + 1/2
x = 19/2 = 9.5
