There are total 80 dimes in the jar. B/c...
n+d=200 = n=200-d
0.05n+0.1d=$14.00
0.05(200-d)+0.1d=$14.00
10-0.05d+0.1d=$14.00
10+0.05d=$14.00
-10 -10
0.05d=$4.00
0.05d/0.05=$4.00/0.05
d=80

Answer:
$300
Step-by-step explanation:
15% / 3 = 5%
45 / 3 = $15
5% * 2 = 10%
15 * 2 = $30
10% * 10 = 100%
30 * 10 = $300
300 x 0.85 (-15%)
255
255 + 45 = 300
Answer:
2.50
Step-by-step explanation:
The average rate of change over the interval −2≤x≤2 is:
(f(2) − f(-2)) / (2 − -2)
From the table, we see that f(2) = 14 and f(-2) = 4.
(14 − 4) / (2 − -2)
10 / 4
