$400$

B.

$130$

D.

$90$

Accepted Answer

Choice B is correct. It&rsquo;s given that the film club has 90 members on the first day of a semester, and 10 new members join the film club each day after the first day of the semester. This means that after 4 days, 4 &#215; 10 , or 40 , new members will have joined the club. Adding 40 members to the original 90 club members yields 130 members. Thus, the film club will have 130 total members 4 days after the first day of the semester. Choice A is incorrect. This is the number of members that will have joined the film club 4 days after the first day of the semester if 100 new members, not 10 , join the film club each day. Choice C is incorrect. This is the number of members the film club will have 4 days after the first day of the semester if 1 new member, not 10 , joins the film club each day. Choice D is incorrect. This is the number of members the film club has on the first day of the semester.
