Question

If a man earns $420 interest in one year at 7%, what was the amount of money invested?



$29.40

$60.00

$600.00

$6,000.00

Answer 1

Let's say that the total money invested is \(x\).
7% of the total money is 420, right?
\( \color{Black}{\Rightarrow 0.07x = 420 }\)
Solve for \(x\).

Answer 5

\( \color{Black}{\Rightarrow 420 \div 0.07 = x }\)

Answer 8

You can work with fractions too!

\( \color{Black}{\Rightarrow \Large \cancel{420} \times {100 \over \cancel7} }\)

\( \color{Black}{\Rightarrow 60 \times 100 }\)
