Exactly 120 tickets were sold for a concert. the tickets cost $12 each for adults, $10 each for seniors, and $6 each for children the number of adult tickets sold was equal to the number of child tickets sold. given that the total revenue from the ticket sales was $1100, the number of senior tickets sold was
a: 110
b: 20
c: 40
d: 2
e: 18

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.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
