You can put this solution on YOUR website!
let a = the youngest
let b = age of the triplets
let c = the oldest
:
Write an equation for each statement
:
"the youngest is in third grade
a = 8 yr is the youngest
:
" the oldest is twice as old as the youngest"
c = 2(8) = 16 yrs is the oldest
:
" the triplets are four years younger that the oldest"
c = 16 - 4 = 12 yrs are the triplets
:
the product of all the children's ages is 221,184
8 * 16 * 12^3 = 221184, that's true
