For a smoothie, Isaac needs 3 quarts of strawberry puree, which is sold in bottles of 1 pint and bottles of 1 cup. He already had 1.75 quarts of puree. If he wants to buy exactly three bottles in total, how many of each bottle should he buy?

Okay, so first let's look at the conversion factors of these units: 1 quart=2 pints & 1 quart= 4 cups. Alright well, we already have 1.75 out of 3 quarts of the strawberry puree so all we need left is 1.25 quarts left. So since 1 pint= .5 quarts and 1 cup=.25 quarts we need to buy 2 pints and 1 cup to give us our three quarts.

Answer: There are 2 bottle of 1 pint and 1 bottle of 1 cup.

Step-by-step explanation:

Let the number of bottles of 1 pint be 'x'

Let the number of bottles of  1 cup be 'y'.

As we know that

\(1\ pint=0.5\ quarts\\\\1\ cup=0.25\ quarts\)

According to question,

\(x+y=3-----(1)\\\\0.5x+0.25y=3-1.75=1.25\\\\x+0.5y=2.5---------(2)\)

From Equation (1), we get that

\(x=3-y\)

Put it in the equation (2),

\(x+0.5y=2.5\\\\3-y+0.5y=2.5\\\\3-0.5y=2.5\\\\-0.5y=2.5-3=0.5\\\\y=1\)

and the value of x will be

\(x=3-y=3-1=2\)

Hence, there are 2 bottle of 1 pint and 1 bottle of 1 cup.
