The science club went on a two-day field trip. the first day the members paid $70 for transportation plus $11 per ticket to the planetarium. the second day they paid $90 for transportation plus $8 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.

$(160 + 19 n)  is the expression to represent the total cost for two days for n students .

Step-by-step explanation:

Let total  number of student who went to the planetarium   = n

Expenses of the FIRST DAY:

Transportation Price = $70

and ticket per head = $11

So, the price for ticket for n students =  11n

So, total expense for First day = $(70  +11 n)

Expenses of the SECOND DAY:

Transportation Price = $90

and ticket per head = $8

So, the price for ticket for n students =  8n

So, total expense for First day = $(90  + 8 n)

Hence, Total cost for TWO DAYS

= Expense of 1st day  +  Expense of 2nd day

= ( $70  +11 n)  +  ($90  + 8 n)   = $(160 + 19n)

Hence,  $(160 + 19n)  is the expression to represent the total cost for two days .
