Problema Solution
Richard works at an ice cream shop. Regular cones get 2 scoops of ice cream; large cones get 3 scoops. 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 weighs 10 pounds. How many tubs of ice cream did Richard use to make the cones?
Answer provided by our tutors
234 regular cones have: 234*2 = 468 scoops (2 scoops each)
156 large cones have: 156*3 = 468 scoops (3 scoops each)
there are total of: 468 + 468 = 936 scoops
One scoop of ice cream is 3 ounces thus 936 scoops of ice cream are:
936*3 = 2808 oz
1 lb = 16 oz
1 oz = 1/16 lbs
2808 oz = (2808)(1/16) lbs = 175.5 lbs
A tub of ice cream weighs 10 pounds and let 'x' be the number of tubes used, x is integer:
10x = 175.5
x = 175.5/10
x = 17.55 tubes
since x is integer x must be 18
Richard used 18 tubes of ice cream.
