Answer 1

180 points.

Explanation:

Given:

A class will have 1 test and 5 homework assignments to complete.

The test is worth 80 points.

Each homework assignment is work 25% of the test.

Question asked:

How many points may be earned during this unit ?

Solution:

By unitary method:

Points may be earned from 1 assignments =
`25\% of 80` (given)

=
`(25)/(100) * 80 = (2000)/(100) = 20`

Points may be earned from 5 assignments =
`5* 20 = 100`

Points may be earned from 1 test =
`80`

Total points may be earned = 100 + 80 = 180

Therefore, 180 points may be earned during this unit.
