A music competition on television had five elimination rounds. After each elimination, only half of the contestants were sent to
the next round. The table below shows the number of contestants in each round of the competition: x 1 2 3 4 5 f(x) 64 32 16 8 4 Compute the average rate of change of f(x) from x = 3 to x = 5 and describe what it represents. −6 contestants per round, and it represents the number of contestants who will reach the final round −28 contestants per round, and it represents the number of contestants who will reach the final round −6 contestants per round, and it represents the average rate at which the number of contestants decreased from the third round to the fifth round −28 contestants per round, and it represents the average rate at which the number of contestants decreased from the third round to the fifth round
M = (Y-y)/(X-x) m = (4-16)/(5-3) m = -12/2 m = -6 <span>it represents the average rate at which the
number of contestants decreased from the third round to the fifth round </span>
$227.50. First, you convert 30% into a decimal: 0.30. Then, you multiply 325.00 by 0.30. This equals 97.50. 97.50 is 30% of 325, so you need to subtract 97.50 from 325.00. This equals $227.50.
