<PRE><B>Question 164323</B>
Let m=amount of extra meat
Cost of the extra meat=0.30m

Now we are told that the cost of the basic sub(5.35) plus the cost of the extra meat(0.30m) equals 6.55.  So, our equation to solve is:

5.35+0.30m=6.55  subtract 5.35 from both sides
5.35-5.35+0.30m=6.55-5.35  collect like terms

0.30m=1.20  divide each side by .30
m=4 ounces---------------amount of extra meat that he ordered

CK
5.35+4*0.30=6.55
5.35+1.20=6.55
6.55=6.55

Hope this helps---ptaylor</PRE>
