Question

Josh and Daniel each want to save $600 to attend a sports camp. Josh has saved 60% ofthe amount. Daniel has saved $320. Who has saved more money? How much more?

Answer 1

The total amount to save is $600

Josh saved 60%. This is the same as below

$\begin{gathered} 60\text{ \% of \ 600} \\ =\frac{60}{100}\times600 \\ =\frac{36000}{100} \\ =360 \end{gathered}$$\begin{gathered} \text{ 60\% } \\ =\frac{60}{100}=\frac{360}{600} \end{gathered}$

Josh has saved $360.

Daniel has saved $320

It can be observed that $360 is more than $320, so Josh saved more money

The difference tells how much more

$\begin{gathered} \text{ \ 360 - \ 320} \\ =\text{ \ 40} \end{gathered}$

Hence,

1. 60/100= x/600

2. Multiply both sides by 600

3. Josh has saved $360

4. Josh saved more money. Josh saved $40 more than Daniel
