Given:

(i) After the outbreak of a mysterious disease, the average wait time at a hospital increased by 70%.

(ii) Before the outbreak, the average wait time at the hospital was m minutes.

To find:

(i) The expressions representing the average wait time at the hospital after outbreak.

= 1.7m minutes

So, option (b) and (e) are correct.
