Question

8 pounds of bananas cost $24. How much would 31 pounds cost

Answer 1

31 pounds cost $93

Step-by-step explanation

you can easily solve this by using a rule of three.

Step 1

Let x represents the cost for 31 pounds,the proportion is

`(x)/(31)`

Now

`\begin{gathered} 24\text{ usd}\rightarrow8\text{ Pounds} \\ \text{the proportion must be the same, then} \\ (24)/(8)=(x)/(31) \\ 3=(x)/(31) \\ \end{gathered}`

Step 2

solve for x

`\begin{gathered} 3=(x)/(31) \\ x=3\cdot31 \\ x=93 \end{gathered}`

Hence, 31 pounds cost $93
