Let x = # of 25-cent stamps
y = # of 2-cent stamps
{ x+ y = 88
{ 0.25x + 0.02y = 15.56
60 25-cent stamps 28 2-cent stamps
t = mr^2/3
Divide both sides by r^2/3
m = t / r^2/3

Grouping method works best on this one:
<span>ab+a+4+4b=a<span>(b+1)</span>+4<span>(b+1)</span></span>
<span>=<span>(a+4)</span><span>(b+1<span>)
</span></span></span>
