The ratio of the amount of money Cara, Janet, and Jerry have is 4:5:6. If the total amount of money they have is $75, calculate the loss Cara and Janet will make if they combine their money to buy oranges and sell them at 80% of the buying price.
The sum of the ratios representing the amount of money the three has is 4+5+6=

<output>15</output>
15.
If the total amount of money they have is $75, the amount of money Cara has represented by the fraction 4/15 is 4/15*$75=$
<gadget id="calculator">4/15*75</gadget>
<output>20</output>
20.
Similarly, the amount of money Janet has represented by the fraction 5/15 of the total ratio is 5/15*$75=$
<gadget id="calculator">5/15*75</gadget>
<output>25</output>
25.
Combined, Cara and Janet have $20+25=$
<gadget id="calculator">20+25</gadget>
<output>45</output>
45.
If Cara and Janet buy goods worth $45 and sells them at 80% of the buying price, the selling price of the goods will be 80/100*$45=$
<gadget id="calculator">45*80/100</gadget>
<output>36</output>
36.
Since they bought the goods at $45 and sold them at $36, Janet and Cara would run at a loss of $45-$36=$
<gadget id="calculator">45-36</gadget>
