Question

For a store contest, 4 out of every 65 people who visit the store will receive a free DVD if 455 people visit how many DVDs were given away

Answer 1

28 people will get a free DVD because 455/65=7 and 7*4=28

Answer 2

28 DVDs will be distributed.

Explanation:

For a store contest out of 65 people 4 people receive a free DVD.

We have to calculate the number of DVDs distributed when 455 people visit the store.

We will apply the unitary method to find the number of DVDs distributed.

∵ When 65 people visit the store number of DVDs = 4

∴ when 1 person visit the store then number of DVDs distributed =
`(4)/(65)`

∴ When 455 people visit the store then DVDs distributed =
`(4* 455)/(65)`

= 28

Therefore, 28 DVDs will be distributed.
