This certainly has a tricky set-up . . .
Let = number of servings of juice sold: .1000 guests at a fundraiser.
$1 for juice, $1.75 for soda
Let = number of servings of soda sold: .
We have: .Each drink has to be served in an unused plastic cup of which there are 5,000
It says: .Juice is at least 30% of (Juice + Soda)Juice must account for at least 30% of drinks served
So we have: .
. . This becomes: .
There are 1000 guests.Each guest can only have 3 sodas
If each has 3 sodas, 3000 sodas will be sold: .
There will be: . ice cubes used.Each juice must have 2 ice cubes and each soda must have 4 ice cubes.
There are 15,000 ice cubes available.
