Question

The expression 0.4a represents the reduced attendance on the second night of a play. Which expression is equivalent to the reduced attendance if a is the attendance on the first night?

Answer 1

c

Explanation:

There are let's say 100 people who came on the first night, and on the second night, only 40 people came, which means that 60 people didn't come. so it's 100-60, which is the same as the third, a-0.6a.
