tom plans to save twice as much next month as he did during the months he saved over $30 a month. how much will tom save next month?

Question

It’s elementary school work.

Answer 1

If he saved 'over $30 a month' previously and wants to save twice as much next month, it depends in part by just what is meant by 'twice as much'. There are 2 possibilities:

Twice as much as he had previously saved in a month would mean he would now save over $60

Twice as much as he had previously saved altogether would also depend on how many months he had been saving so far. If he had been saving for M months, then next month he would save over 2*60M or 120M. 

In both cases, an exact answer is impossible, since we are only told he saved 'over $30 a month', not an exact amount
