How Do You Figure These Out. I Need Lots Of Help?
By1. Joe has a collection of nickels and dimes that is worth $6.05. If the number of dimes was doubled and the number of nickels was decreased by 10, the value of the coins would be $9.85. How many dimes does he have?
2. An express train and a local train both leave Gray’s Lake at 12:00 noon and head for Chicago 60 miles away. The express travels twice as fast as the local and arrives 2 hours ahead of it. Find the speed of each train.
3. One year ago Walt invested $12,000. He invested part of the money at 7% and the rest at 9%. He made a total of $970 in interest. How much was invested at 7%?

1. He only has 2 because collecting nickels and dimes is stupid and his little brother stole all his money to buy a new rubber ducky.
2. You can’t figure this problem out until you know how much friction was caused by the train driving underwater in the lake.
3. Walt Disney invested WAY more than $12,000. He needed to get so muh money to get Mickey those ear implants
