How much is the estimated cost?

Hint:

When we are estimating, we are not looking for an exact answer, but to have a rough idea (slightly more slighttly less).

We are also trying to make our lives easier by using easier numbers to work with. To estimate we use rounding.

Here we are going to round £29.95 to the nearest 10....

Then times it by the number of people and that will give us our estimate.

Back

Answer:

£29.95 will round up to £30.

30 x 6 = 180

The estimated cost is £180.
