Question 1109427: Inflation causes things to cost more, and for our money to buy less (hence your grandparents saying "In my day, you could buy a cup of coffee for a nickel"). Suppose inflation decreases the value of money by 5% each year. In other words, if you have $1 this year, next year it will only buy you $0.95 worth of stuff. How much will $100 buy you in 20 years?

You can put this solution on YOUR website!
Let +V+ = value of the money
after 20 yrs
+V+=+100%2A%28+1+-+.05+%29%5E20+
+V+=+100%2A.95%5E20+
+V+=+100%2A.3585+
+V+=+35.85+
In 20 yrs $100 is worth $35.85
