What is Unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value

We have,

Mrs. jenkins sold= 300 tickets for £3 each

The price of total tickets sold=300x3=900

As, The probability that someone wins a prize is 0.2.

So, 300 /0.2

= 60

Each prize cost £8.so,

=60x8

=480

Thus,

900-480=420

Hence, Mrs Jenkins would give £420 to charity.
