The Science Club went on a two-day field trip. The first day the members paid $60 for transportation plus $11 per ticket to the planetarium. The second day they paid $100 for transportation plus $8 per ticket to
the geology museum. Write an expression to represent the total cost for two days for the n members of
the club.

3/8

Step-by-step explanation:

Step 1: Multiply the denominator and the numerator of 1/4 by 2 to get a common denominator between the two. (1/4 and 5/8 is now 2/8 and 5/8)

1*2= 2; 4*2= 8, so you get 2/8 (which is equal to 1/4)

Step 2: When you get 2/8, subtract:

5/8 - 2/8 = 3/8

And... since 2/8 is equal to 1/4, 3/8 is the answer :)

Hope this helps :)
