Question 1013344
b and c, the counts of birds and of cats;


{{{system(b+c=31,2b+6.5c=120.5)}}}----the description translated into a system of equations, to account for total birds and cats, and the cost that day.


You can try the system this way:
{{{system(b+c=31,4b+13c=241)}}}, partly preparing for Elimination Method, and then


{{{system(4b+4c=124,4b+13c=241)}}}----Now eliminate b and find c.
