The packages in a mail driver’s truck weigh a total of 950 pounds. The large packages weigh 20 pounds each and the small packages weigh 10 pounds each. If he has 10 more large packages than small packages, how many large and small packages are on the truck?
+36915 x = small pkgs
10x = weight of small pkgs
x+10 = # lge pkgs
20(x+10) = wt of lge pkgs
10x + 20(x+10) = 950 pounds
30x + 200 = 950
30x = 750
x = 25 small packages x+10 = 35 large packages
