Question 1095724
r, rib-eye steak price
p, salmon price  (PHish, Pesca)

{{{system(17r+24p=593.54,25r+8p=584.21)}}}


It looks like a system not too neat to solve; but try tripling the members of the "Another day" equation.
{{{system(17r+24p=593.54,50r+24p=1752.63)}}}

Subtract first equation from second equation, eliminating p:
{{{50r+24p-17r-24p=1752.63-593.54}}}

.

. 
Do the steps and use result to find p; and see if you get meaningful results.
