The cost of a ticket to an amusement park is $42 per person. for groups of up to 8 people, the cost per ticket decreases by $3 for each person in the geoup. marco's ticket cost $30. write and solve an equation to find the number of people in marco's group.

X is the amount of groups
y is the amount of people

42- 3x = 30

x (8) = y

42 - 3x = 30
-42 -42
-3x = -12
divide by -3
x = 4, there were 4 groups of 8, substitute the 4 into the other equation

4×8 = 32
y = 32 , There are 32 people in Marcos group

sorry, it's the best I could do.

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
