Here is an equation for you!:

Some kids on the beach is selling crabs to tourists. It is very fun and they are making a lot of money because they have 20 buyers everyday who buys one crab each. They have decided that the price for one crab will go up a bit per day. How many per cent have they chosen?

Income for 10 days: I=12383 dollars

Price per crab the first day: n=10 dollars

Rise per day in per cent: r=?

Number of days: t=10

Number of buyers in all: b=200

The equation is: I=n (1+ r)^t * b

Please tell us if this exercise is too easy or too difficult so we know next time how we can make it better!
