Nate spent 1/3 of his money on 6 curry puffs and 13 apple pies.
The cost of 1 apple pie is twice the cost of a curry puff.
He bought more apple pies with 3/4 of the remaining money.
He paid a total of $92.50 for all the apple pies.
How much did Nate pay for 1 apple pie?
Answer: He payed $2.50 for one apple pie.
The second line elimates the need for curry puffs. I can just right 1/2 apple pie instead. Or, in the case of the first line, 3 curry puffs.
Let m be the original amount of money. Let a be the number of apple pies.
m/3 = 16a
m = 48a
1/6 of the money he kept.
48 * 5/6 = 40
3 of the pies were actually curry puffs.
40 - 3 = 37
92.5 / 37 = 2.50
