Claude is reading a science fiction book in which aliens have dropped a fungus on a 10 square mile section of a
planet. The fungus spreads rapidly, increasing the area it
covers by 50% every hour. The total area of the planet is
200 million square miles. Claude created an equation and determined that it will take approximately 41 hours for the fungus to cover planet. What is the equation that Claude
created?

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
