Problem of the Week 6/7

Jun 7, 2017

Check out our Facebook @mathnasiumofwestlexington for the question! 

Here's the answer:

Answer: 750 gallons
Solution: If 1/4 of the water in a 4/5–full tank leaks out, then the tank is now 3/5 full. If 450 gallons makes up 3/5 of the tank’s capacity, then 1/5 of it must be 450 ÷ 3 = 150 gallons. 150 gallons, 5 times makes 5/5 of the tank’s capacity, and 150 × 5 = 750 gallons.
