Tim had $1200 more than Jenny. After giving $\frac{1}{3}$ of his money to Jenny, he had $3400 left. How much money did Jenny have at first? Ans: $ ___

1. Find the fraction of money Tim had left

Fraction left = $1 - \frac{1}{3} = \frac{2}{3}$

2. Calculate Tim's initial amount of money

$\frac{2}{3}$ of Tim's money = $\char36{}3400$
Tim's initial money = $\char36{}3400 \div 2 \times 3 = \char36{}5100$

3. Calculate Jenny's initial amount of money

Jenny's initial money = $\char36{}5100 - \char36{}1200 = \char36{}3900$
