Write an equation for each phrase, get all three in terms of b
:
divide $1500 between a,b and c
a + b + c = 1500
:
such that b share is five-sixth of a share
b = a
multiply both sides by 6
6b = 5a
divide both sides by 5
a = b
:
and c share is four-fifth of b share
c = b
:
Now we substitute for a and c and have:
b + b + b = 1500
multiply by 5, get rid of the denominators
6a + 5b + 4b = 5(1500)
15b = 7500
b = 7500/15
b = $500 is b's share
then
a = *500
a = $600 is a's
and
c = *500
c = $400 is c's
:
They add up to $1500
