Andrew spent $940 on a laptop and 57of the remaining money on a printer. His father gave him $240 and the amount of money he had at the end was 29 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.
