There are 21 juice bottles out of which 7 bottles are full. 7 are half-full and the remaining 7 are empty to divided amongst 3 friends equally. You don't have any measuring device. After dividing them ( both bottles and juice ) equally how mach empty bottles each will get?

each friend would have 3 and 1/2 bottles of juice meaning each friend would have 3 fully empty bottles.

$9.41

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
