Question

john had $200. David had $180. After they each spent an equal amount of money, the ratio of john's money to david's money was 3:2. how much did each of them spent?

Answer 1

$140

Explanation:

After they spent an equal amount, John has $200 - x and David has $180 - x left.

According to the given information, the ratio of John's money to David's money is 3:2, which can be expressed as:

(200 - x) / (180 - x) = 3/2

To solve this equation, we can cross-multiply:

2(200 - x) = 3(180 - x)

Expanding the equation:

400 - 2x = 540 - 3x

Rearranging the terms:

3x - 2x = 540 - 400

x = 140
