The seventh grade math classes are going on a field trip. The field trip will cost the school $7 per student plus a one time fee of $55 for a bus to rent.
The total cost of the field trip was $307. Write an equation to find the total
number of students that went on the field trip.
62s = 307
55s + 7 = 307
7s + 55 = 307
75 -55 = 307

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
