Write an equation for each statement
:
"Billy has 3 times as much money as Reagan."
b = 3r
:
" Madison has 4 times as much money as Reagan."
m = 4r
:
"Madison has $21 more than Reagan,"
m = r + 21
Note that m = 4r and (r+21) so we can solve for r (m=m)
4r = r+21
4r - r = 21
3r = 21
r = 21/3
r = $7 is Reagans amt
then
b = 3(7)
b = $21
and
m = 4(7)
m =$28
:
how much money do they have altogether?
7 + 21 + 28 = $56
