The Johnson family is preparing to vacation at a famous amusement park. The park offers a family ticket discount package for an unlimited number of rides and will charge an entry fee for each person in the family. The equation below represents the cost per person, C(x), as a function of the number of
people in the family, X.
C (x)= 160/x + 7.5
If each person in the Johnson family paid $27.50, how many people were in the family?
12 people
5 people
14 people
8 people

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
