Question

The Science Club went on a two-day field trip. The first day the members paid $60 for transportation plus $20 per ticket to the planetarium. The second day they paid $100 for transportation plus $17 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.

Answer 1

Here, we want to represent the total cost for the two-day field trip of the science club. if we let x be the number of members in the club, We then come up with the following expressions

For day 1: $60+$20x

For day 2: $100+$17x

Therefore, the cost of c for the two-day field trip is just the sum of equations 1 and 2 that is,

C= Cost for day 1 + cost for day 2

C= $60+ $20x + $100+ 17x

combine like terms to get

$80+$117x
