Answer:

a)  14

b)  9

c)  10

Step-by-step explanation:

Part (a)

Given:

  • 1 bag = 126 g of buttons
  • Weight of Button A = 9 g

⇒ Number of Button As in one bag = 126 g ÷ 9 g = 14 buttons

Part (b)

Given:

  • 1 bag = 126 g of buttons
  • Weight of Button B = 14 g

⇒ Number of Button Bs in one bag = 126 g ÷ 14 g = 9 buttons

Part (c)

Given:

  • The box contains 230 g of buttons
  • The box contains the same number of each type of button

Let x = number of buttons of each type.

⇒ 9x+ 14x = 230

⇒ 23x = 230

⇒ x = 10

Therefore, there are 10 of each type of button in the box.
