Question

Jane needs $20 to buy her radio.She has saved $15.What precent of the cost of the radio has she saved?

Answer 1

Let's begin by listing out the information given to us:

Cost of Radio (c) = $20

Jane's saving (s) = $15

% of radio cost saved = (Jane's saving / Cost of Radio) * 100%

`\begin{gathered} x=(s)/(c)\cdot100 \\ x=(15)/(20)\cdot100=75 \\ x=75 \end{gathered}`

Jane has saved 75% of the radio cost
