Answer provided by our tutors
c = the number of cans collected
b = the number of bottles collected
they collected 1500 cans and bottles
c + b = 1500
they raised 147$ that is
0.3c + 0.05 b=147
by solving the system of equations
c + b = 1500
0.3c + 0.05 b=147
we find
c = 288 cans
b = 1212 bottles
the collected 288 cans and 1212 bottles.
