Answer:
$20.25 Dollars
Explanation:
keep in mind:
1 pint = 2cups
1 quart = 4cups
according to the story, she buys 2 pints of blue(4 cups), 3 cups of green(3cups),
1 1/2 quarts (6cups), and 1/2 cups(I am assuming cups because it wasn't stated)
so now we just add up all the cups using the measurements I stated at the beginning.
13.5 cups is the amount she is buying, but we need to know the price, so we simply add $1.50 for every cup she bought!
1.50 x 13.5 = 20.25
So the answer is $20.25 Dollars
