i don't understand the question a and b. so question a, it have to be add all?
When he was young, Captain Conundrum mowed lawns on weekends to help pay his college tuition bills. He charged
his customers according to the size of their lawns at a rate of 5¢ per square foot and meticulously kept a record of
the areas of their lawns in an ordered list:
A=(200,300,50,50,100,100,200, 500,1000,100)
He also listed the number of times he mowed each lawn in a given year, for the year 1988 that ordered list was
f =(20,1,2,4,1,5,2,1,10,6)
-How much did Captain Conundrum earn from mowing lawns in 1988? Write an expression for this amount in
terms of the vectors A and f.
-Suppose Captain Conundrum charged di�erent customers di�erent rates. How could you modify the expression
in part 1c to compute the Captain's earnings?
