A-Plus Auto Body is painting flames on a customer's car. They need 2 1/2 pints of red, 3 pints of orange, 3/4 pint of yellow, and 7 pints of blue paint. They use 3/4 of the blue paint to make the flames. They need 7 3/4 pints to paint the next car blue. How much more blue paint will they need to buy???
You will need one and a half pints more of paint because you start with 7 then subtract .75 to get 6.25 from there you need seven three fourths pint for the next car so you subtract 7.75 - 6.25 to get 1.5
