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

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
