Lucas brought $164 to the store. He has already spent $147.50, but still needs to buy some gallons of milk that cost $2.79 each.
What is the maximum number of gallons of milk that Lucas could buy (not including tax)?
First, let's find the remaining money.
164-147.5 = 16.5
So, he has $16.50 left.
Now, we take 16.5 and divide it by 2.79. This will give the amount of milk he can buy
16.5/2.79 = 5.9139784946236559
Well, we can't buy a part of a milk jug, so we have to round DOWN since we can't just get milk for free as well.
So, Lucas can buy 5 gallons of milk with a remaining amount of $2.55. Maybe buy some candy for all the hard work he's gonna be doing?
