Answer 1

Step-by-step explanation:

The ratio of $50 and $20 notes = 3:5

Therefore, let the number of $50 notes be = 3x

and $20 notes be = 5x

Since the total number of notes is = 25

Therefore, the number of $10 notes = 25 - (3x + 5x ) = 25 - 8x

Value of $50 notes = $50 * 3x = $150x

Value of $20 notes = $20 * 5x = $100x

Value of $10 notes = $10( 25 - 8x)

= $250 - 80x

Since the total value of notes = $590

Therefore, 150x + 100x + 250 - 80x = 590

=> 250x - 80x = 590 - 250

=> 170x = 340

=> x = 2( because 340 ÷ 170 = 2 )

Therefore, number of $50 notes = 3 * 2 = 6

number of $20 notes = 5 * 2 = 10

number of $10 notes = 25 - (6+10) = 9..
