Answer:
C
Step-by-step explanation:
You have to do change of y over change of x, substitute the numbers to get 0.30-0.90 for y then 1-3 for x, get -0.06/-2 and solve that to get 0.3 per pound per year, which is answer C
X + y = 5
x - y = 1
--------------add
2x = 6
x = 6/2
x = 3
x + y = 5
3 + y = 5
y = 5 - 3
y = 2
the solution is (3,2)
