The Charleston family has less than 500 Dalmatians. There are six times as many Dalmatians with black spots on their right ears as Dalmatians without these spots. After giving away 6% of their Dalmatians, how many do the Charlestons have left?
Let x be the number of Dalmatians without black spots. So, x+6x is close to 500, which means x=71. 71*7=497, which is the total number of Dalmatians. Giving away 6% of this will give you around 467 Dalmatians left.
