well if tina's age is T, then the next one must be T+2, the next T+4

now..ask yourself..in the first equation.. why was T+2 multiplied by 2 and T+ 4 by 4? where in the problem was it stated to do so?

Those where just the examples and we had to pick one that fit

yeah...well forget what i said..T = tina's age; T+2 = next child; T+4 = next child because each one has 2 yr difference..the problem said sum of ages of all three children..disregard the choices..how will you do this?
