Question

A certain species of fish costs $5.49 each. You can spend no more than $30. How much of this type of fish can you buy for you aquarium?

 

Answer 1

We can round up to 5.50 to make the math simpler. If the fraction is near the cusp of reaching the next whole number, then we can recalculate with the original 5.49.

30 / 5.5  = 5.45......

 

We cannot purchase part of a fish, so we round down to 5.
