four brothers each received $20.00 for helping neighbors with yard work. the names below show how much of their money each brother spent!josh: 30%ralph: 1/4marcus: 20%trevor: $4.50Which brother spent the most?

Answer 1

We need to find how much each brother spent.

Josh:

To find how much he spent we use the rule of three:

`\begin{gathered} 20\rightarrow100 \\ x\rightarrow30 \end{gathered}`

then:

`x=(30\cdot20)/(100)=6`

Hence Josh spent $6.

Ralph:

To find how much money he spent we divided the $20 by 4, then:

`(20)/(4)=5`

Hence Ralph spent $5.

Marcus:

To find how much he spent we use the rule of three:

`\begin{gathered} 20\rightarrow100 \\ x\rightarrow20 \end{gathered}`

then:

`x=(20\cdot20)/(100)=4`

Hence Josh spent $4.

Trevor:

The problem already said that he spent $4.50.

Comparing how much each of them spent we conclude that Josh spent the most.
