XYZ Music Store sells new CDs, n, for $12.25, and used CDs, u, for $5.75. The store earned $765 revenue last month. The store sold 22 more used CDs than
new CDs. Which system of equations represents this scenario?

B.

Step-by-step explanation:

12.25 for n CD's

5.75 for u CD's

the total is 765

22 are more sold for more used than new

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
