Ann, Scott, and Greg have a total of
$123
in their wallets. Ann has
$8
less than Scott. Greg has
3
times what Ann has. How much do they have in their wallets?
Answer provided by our tutors
Let
a = the amount that Ann has
s = the amount that Scott has
g = the amount that Greg has
Altogether they have $123:
a + s + g = 123
Ann has $8 less than Scott means:
a = s - 8
Greg has 3 times as much as Ann means:
g = 3a
We have the following system of equations:
a + s + g = 123
a = s - 8
g = 3a

a = $23
g = $69
s = $31
Ann has $23, Scott has $31 and Greg has $69.
