Brain Ruilders 3. Four gallons of paint are used to paint 20 chairs and 5 small tables. If each chair and table used the same amount of paint, how many gallons are used to paint each piece of furniture? Between what tw whole numbers does your answer lie?

To find out how many gallons of paint are used for each piece of furniture, we first need to calculate the total number of pieces: 20 chairs + 5 small tables = 25 pieces. With 4 gallons of paint for 25 pieces, we divide 4 gallons by 25 pieces, which gives us 0.16 gallons per piece. This number lies between the whole numbers 0 and 1. Now, when working with paint, it's easy to spill a little or miscalculate. A common mistake is assuming each item uses the same paint without considering different surface areas or textures. Always measure and apply a test coat first to avoid underestimating the amount needed!
