Answer: the number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
Step-by-step explanation: This is the equation
16 * (28 - y) + 10 * y = 40016 * 28 - 16 * y + 10 * y = 400448 - 400 = 16 * y - 10 * y48 = 6 * y /6y = 48 / 6y = 8x = 28 - y = 28 - 8 = 20Result: The candle shop sold 20 scented candles and 8 unscented candles today.

Step-by-step explanation:
He fish weighs 7 x 8 ounces = 56 ounces
With n tosses, there are a total of 2^n possible outcomes. We need 15 of theses to be heads.
Since the tosses are random, we want to count the ways to have exactly 15 of them being heads. That will be C(n,15) ways to pick which tosses are heads.
The probability will be given by:
C(n,15)/2^n=0.0148
At this point we use various values of n until we get the correct probability.
n=18⇒0.003112793
n=19⇒0.007392883
n=20⇒0.014785767
n=21⇒0.025875092
Answer:
n=20
