Problema Solution
Cora went fishing. The sea trout weighed twice as many pounds as the redfish. The redfish weighed twice as many pounds as the snook. Core caught a total of 21 pounds. How much did the snook weigh
Answer provided by our tutors
let
t = lbs of sea trout
r = lbs of red fish
s = lbs of snook
The sea trout weighed twice as many pounds as the redfish
t = 2r
The redfish weighed twice as many pounds as the snook
r = 2s
Core caught a total of 21 pounds
t + r + s = 21
by solving the system of equations
t = 2r
r = 2s
t + r + s = 21
we find
t = 12 lbs sea trout
r = 6 lbs redfish
s = 3 lbs snook
