Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.
This is an example of an exponential equation. These equations are always in the form y = ab^x.
The a value is the starting value. The b value is the interest rate. The x value is the number of years.
The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.
Answer:
-8p + 7
n = --------------
8 - 5p
Step-by-step explanation:
Let's group the n terms in 5pn-8p=7n-7 .
Subtract 5pn from both sides. This results in -8p = 7n - 7 - 5pn
Now add 7 to both sides. This will group the n terms on the right side:
-8p + 7 = 7n - 5pn
Factor n out of 7n - 5pn:
-8p + 7 = n(7 - 5p)
Finally, divide both sides by (7 - 5n) to isolate n:
-8p + 7
n = --------------
8 - 5p
Answer:
Step-by-step explanation:
Unit rate per fluid ounce = $0.15
Step-by-step explanation:
Given that:
Cost of one quart bottle of juice = $4.80
We know that:
One quart = 32 ounces
Unit rate is the rate in which two quantities are compared and one of them is one.
Unit rate =
Unit rate = $0.15 per fluid ounce
Hence,
Unit rate per fluid ounce = $0.15
