Question 1159947

A company that sells pocket radios makes a profit of R 12 000 on the first 500 radios sold.
Assuming that all prices remain the same, how much profit do you expect to make on selling 7000
radios?
<pre>The following PROPORTION is all that needs to be set up: {{{matrix(1,3, "12,000"/500, "=", P/"7,000")}}}, with P being PROFIT
{{{matrix(1,3, 24cross("12,000")/1cross(500), "=", P/"7,000")}}}

Cross-multiplying, we get PROFIT from selling 7,000 radios, or {{{highlight_green(matrix(1,6, P, "as:", 24("7,000"), "=", R, "168,000"))}}}</pre>
