Answer 2

• 30 of 25 cent, 10 of 14 cent, 60 of 2 cent

Explanation:

• Note: it must be typo 10.70, changed to 10.10

Number of 25 cent stamps = x

Number of 14 cent stamps = y

Number of 2 sent stamps = z

• Total = $10.10 = 1010 ¢
• x = 3y
• z = 2x ⇒ z = 6y

Solving equation

• 25x + 14y + 2z = 1010
• 25(3y) + 14y + 12y = 1010
• 75y + 26y = 1010
• 101y = 1010
• y = 1010/101
• y = 10

The finding x and z

• x = 3*10 = 30
• z = 6*10 = 60
