So if there are twenty children and 6 have an average age of five, you could say their total age together is 30 years. The others (20-6) have an age of 8.
30+ (20-6)*8 = total age of every child at the library. From there divide by the number of children.
Answer:
Find the rate of change by dividing the value of one term by the value of the preceding term, in your problem:
$15/$10 = 3/2 or 1.5, this is your rate of change
1.5 ($15) = $22.50
Step-by-step explanation:
The CD usually sells for $18.00, and of this price is 10% off, so you would want to first find out 10% of $18.00 is, and subtract that from $18.00
10% of 18.00 is 1.8, so:
$18.00 - 1.8 = $16.20
$16.20 is the price of the CD after a 10% off discount, but you still want to find out the total price with the sales tax.
To find the tax, find 8% of $16.20, and add that amount to $16.20
So:
8% of $16.20 is $1.30
Add $16.20 + $1.30 = $17.50
Thus your final answer is $17.50, which is the total price of the CD, including tax.
