Question

The number of fish caught on a fishing trip varies directly as the number of boats that are fishing. There are 600 fish caught when 15 boats are fishing.

How many fish will be caught if 7 boats are fishing?
A.
105
B.
6
C.
15
D.
280

Answer 1

280 fish because you have to divide 

Answer 2

First you have to find the number of fish per boat.
600 divided by 15 is 40.
then you multiply 40 by 7 to find how many fish for 7 boats.
40 x 7= 280.
280 fish if they use 7 boats.
