One gallon is equal to how many cups

There are 4 quarts in a gallon.  In addition, there are two pints in every quart, so we have 4*2=8 pints.  There are 2 cups in a pint, so there are a total of 8*2=16 cups in one gallon.

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
