Question

The Science Club went on a two-day field trip. The first day the members paid $60 for transportation plus $18 per ticket to the planetarium. The second day they paid $85 for transportation plus $15 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.

An expression that represents the total cost in dollars for two days for the n members of the club is given by _____.

Answer 1

An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n.

Explanation:

To solve this problem, we must first find the constants and variables.

On the first day, the members pay $60 for transportation and $18 per person for a ticket. The $60 transportation is the constant, while the $18 ticket is the variable.

On the second day, the members pay $85 for transportation and $15 per person for a ticket. The $85 transportation is the constant, while the $15 ticket is the variable.

So, now add the constants up (constant + constant) and the variables up (variable + variable).

85 + 60 = 145

15 + 18 = 33

Now add a "n" to the sum of the variables to represent the number of people in the group, "33n".

Finally, write the equation: 145 + 33n

So, the total cost of the two-day field trip would be $145 + $33n
