Question 1015099
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of oranges purchased, so *[tex \Large x] must also represent the number of bananas purchased.  20% of 5 is 1, so he must have sold the oranges for 6 and 15% of 2 is 0.3, so he must have sold the bananas for 2.3.  If *[tex \Large C] represents the total cost of the fruit purchased, then the following relationships must hold:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5x\ +\ 2x\ =\ C]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6x\ +\ 2.3x\ =\ C\ +\ 390]


Solve for *[tex \Large x]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it

*[tex \Large \ \
*[tex \LARGE \ \ \ \ \ \ \ \ \ \
