Andrew spent $940 on a laptop and \( {5 \over 7}{}{}\)of the remaining money on a printer. His father gave him $240 and the amount of money he had at the end was \( {2 \over 9}{}{}\) of the money he had at first. How much did the printer cost?

The amount of money Andrew starts with we set as X

X - 940 - 5/7(X - 940) + 240 = 2/9X

X- 5/7X -2/9X -940 +4700/7+240 = 0

X-5/7X-2/9X= 940-240-4700/7

4/63X = 200/7

4X = 1800

X = 450????

Can someone check my process because either I made a mistake during calculation or there's something wrong with the question. He can't start with 450 and spend 940.
