Question

Carol sold 1/4 as many magazines as Tom. If together they sold 35 magazines, how many did each sell?

Answer 1

C=carol
t=tom

carol sold 1/4 of tom
c=1/4t
c=t/4

together they sold 35
c+t=35
subsitute t/4 for c
t/4+t=35
multiply both sides by 4
t+4t=140
5t=140
divide both sides by 5
t=28

sub back

c=t/4
c=28/4
c=7


carol sold 7
tom sold 28
