Suppose you have $100, which you can invest with a 10% return each year. after one year, its 100 x 1.1 = 110 dollars, and after two years its 100 x 1.1 x 1.1 =121. add code to calculate how much money they end up with after 7 years and print the results.

i believe the question is looking for the calculation to involve exponentiation and modulo.

this code is to be written out in python but if you can't that's fine any would be appreciated

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
