After the journalism club sold 60 magazines, it had $220 in profit. after it sold a total of 100 magazines, it had a total of $420 in profit. which equation models the total profit, y, based on the number of magazines sold, x?
a. y – 220 = 2(x – 60)
b. y + 220 = 5(x + 60)
c. y + 220 = 2(x + 60)
d. y – 220 = 5(x – 60)

What is the measure of angle z in this figure? enter your answer in the box. z = ° two intersection lines. all four angles formed by the intersecting lines are labeled. clockwise, the angles are labeled 43 degrees, x degrees, y degrees, and z degrees.
