Question

A members-only speaker series allows people to join for $28 and then pay $4 for every event attended. What is the total cost for someone to attend 4 events? Write and solve an equation to find the answer

Answer 1

Given:

Joining fee = $28

Fee of each event = $4

To find:

Total cost for someone to attend 4 events.

Solution:

Let the number of events be x and total fee be y.

Fee for 1 event = $4

Fee for x events = $4x

Joining fee remains constant. So, the total fee is

`y=28+4x`

Substitute x=4 in this equation.

`y=28+4(4)`

`y=28+16`

`y=44`

Therefore, total cost of 4 events is $44.
