I will give brainliest PLEASE HELP!! The history museum charges a $20 fee plus $8 per student for a field trip. The
aquarium charges a $50 fee plus $5 per student. The lines in the graph
represent the cost of each field trip.

and what will that cost be?

22 dimes and 9 nickels

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
