Richard works at an ice cream shop. regular cones get two scoops of ice cream; large cones get three 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?

So, let's all put this information about the cones in an immaculate way.

Regular cones => get two scoops of ice cream.
Large cones => get three scoops of ice cream.

On one hot Saturday, Richard scooped 234 regular ice cream cones and also scooped 156 large ice cream cones. 

We know that one ice cream scoop is 3 ounces. And a tub holds 10 pounds of ice cream. Then the question asks, "How many tubs of ice cream did Richard use to make the cones?".

First, we need to convert the pounds of ice cream in ounces because we are working with ounce with ice cream cones.

To convert a pound into ounces, multiply the pounds by 16.

10 * 16 = 160

To make this easy, let's up all the ice cream cone scoops. If a regular has 2 scoops then 234 * 2 = 468

And also with the large ice cream cones.

156 * 3 = 468. 

Now, each scoop is 3 ounces. Multiply 3 ounces by the number of cones there are in total.

(468 + 468) * 3 = 2808

And a tub of ice cream has 160 ounces. So, divide 2808 by 160.

2808 / 160 = 17.55

So, Richard would have needed 17.55 tubs of ice cream.

There's 234 regular so multiple 234 by 2 to get the total scoops which is 468 then multiple by three to get the of ounces 1404. now there's 156 large so you multiple by three to get the total of scoops which is 468 and multiple by 3 to get the ounces which is 1404. now you got the ounces for both you add them together to get total ounces of both which is  2808 then divided it by 10 to get the total number of tubs so there for it is 280.8 tubs
