Richard works at an ice cream shop. Regular cones get 2scoops of ice cream; large cones get 3 scoops of ice cream. one hot Saturday, Richard scooped 234 regular cones and 156 large cones. one scoop of ice cream is 3 ounces. A tub of ice cream weights 10 pounds. how many tubs of ice cream did Richard use to make the cones.

He use 234 to make ice cream cone and it weighs 10 lb

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
