1/2 of 18 pints is 9 because 18/2=9

They have 9 pints left.

1/3 of 18 pints is 6 because 1/3*18=6

9-6=3

There are 3 pints left.

They need 7.75 pints and they only have 3 so 7.75-3=4.75 (or 4 3/4)

They need 4 3/4 more pints of blue paint

A-Plus Auto Body need to buy 4.35 pints or 5 pints if they can buy whole ones.

<h2>Further Explanation</h2>

Total given pints = 18  

Pints of blue paint used for flames =  1/2 x 18 = 18/2  = 9

Pints of blue paint used for sparks =  1/3 x 18 = 18/3  = 6

Total used pints of blue paint =  Pints of blue paint used for flames + Pints of blue paint used for sparks =  9 + 6 = 15

Total used pints = 15

Remainder of blue paint =  Total given pints – Total used pints =  18 – 15 = 3

Remainder = 3

Deriving the total pint they need to buy to paint the next design:

Recall, they need 7 3/4 or 7.35  

Recall, Remainder = 3

Subtract 7.35 – 3  

7.35 – 3 =

4.35

Therefore, A-Plus Auto Body need to buy 4.35 (or 5) pints of blue paint
