Question

38 kg of onions cost $144.40. how much would 49 kg cost?

Answer 1

We apply the rule of three:

kg of onions $

38 ------------------- 144.40

49-----------------------x

First it is 49 x 144,40, and after it is divided by 38, therefore:

`\bf{x=(49*144.40)/(38)= (5605.6)/(38)=186.2 }`

Put so much, 49 kilograms of onion count $ 186.2.

Answer 2

$186.2

Explanation:

38 kg costs $144.40

∴ 1 kg costs =
`(144.40)/(38)` = $3.8

49 kg costs = 3.8 x 49

= $186.2
