Question

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?

Answer 1

Cost of 110 g bag = $ 0.132

Explanation:

As we know ,

1 kg = 1000 g

⇒1000 g = 1 kg

⇒1 g =
`(1)/(1000) = 0.001` kg

⇒110 g = 110 (0.001) kg = 0.11 kg

⇒110 g = 0.11 kg

Now,

Cost of 10 kg bag = $12

⇒Cost of 1 kg bag =
`(12)/(10) = 1.2`

⇒Cost of 1 kg bag = $ 1.2

⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132

∴ we get

Cost of 110 g bag = $ 0.132
