Answer:
Step-by-step explanation:
reg. cones get 2 scoops, lg cones get 3 scoops
he scooped 234 regular cones.....234* 2 = 468 scoops
he scooped 156 lg cones.....156 * 3 = 468 scoops
thats a total of 468 + 468 = 936 scoops
each scoop weighs 3 oz.....so the total weight of the ice cream is :
936 * 3 = 2808 oz
1 lb is 16 oz....so 2808 oz is : 2808/16 = 175.5 lbs
if a tub of ice cream weighs 10 lbs, then richard used :
175.5 / 10 = 17.55.......he used 17.55 tubs full
1/2 and 2/4 I believe those are right
