The Science Club went on a two-day field trip. The first day the members paid $30 for transportation plus $15 per ticket to the planetarium. The second day they paid $95 for transportation plus $12 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

Step-by-step explanation:

day 1-- 30+15= 45

day 2-- 95+12= 107

107+45=152

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
