I have enough money to purchase either 50 apples or 40 oranges. I have...
Given information:

  • Enough money to purchase 50 apples or 40 oranges

  • Decided to spend 90% of the money

  • Purchased 25 apples



To find: Number of oranges purchased

Solution:

  • Cost of 1 apple: Let the cost of 1 apple be x

  • Cost of 1 orange: Let the cost of 1 orange be y

  • Cost of 50 apples: 50x

  • Cost of 40 oranges: 40y

  • Amount of money available: Let the amount of money available be M

  • 90% of the money: 0.9M

  • Cost of 25 apples purchased: 25x



Equation:

As per the given information, the amount of money spent is 90% of the total amount of money available. Therefore,

25x + yz = 0.9M

Also, given that we have purchased 25 apples. Therefore,

25x = cost of 25 apples purchased

Now, we can calculate the cost of 40 oranges as follows:

40y = (0.9M - 25x)

Therefore, the number of oranges purchased is:

Number of oranges = (0.9M - 25x) / 40y

Answer: The number of oranges purchased is (0.9M - 25x) / 40y.
