Question 1162912
<font face="Times New Roman" size="+2">


*[tex \Large \frac{100}{1.22}] is the sum of the cost prices of the two items, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A\ +\ B\ =\ \frac{100}{1.22}]


The sum of the sale prices is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.20A\ +\ 1.25B\ =\ 100]


Solve the 2X2 system for *[tex \Large A] and *[tex \Large B], then calculate *[tex \Large 1.20A] and *[tex \Large 1.25B].

My calculator said it, I believe it, that settles it
