Write a word problem that involves a proportional relationship and needs more than one step to solve.Show how to solve the problem

Answer 1

To write a word problem that involves a proportional relationship:

Sam bought 4kg of apples for $12. How many kilograms of apples, he can buy for $30?

Sam bought 4kg of apples for $12.

So, cost of 1 kg of apples is,

`(12)/(4)=3`

Let x be the number of kg apples.

Therefore, He can buy 3x kg apples for $30.

So,

`\begin{gathered} 3x=30 \\ x=(30)/(3) \\ x=10 \end{gathered}`

Therefore, He can buy 10 kg apples for $30.
