Answer:
21
Step-by-step explanation:
The question states that she in 4 days, makes 14 pots per day on average, and
charges $24 a pot.To find the amount of money she makes in 4 days, find the product of 4, 14 and 24. and that is 1344.
Then equate it to the product of new price, 4 and x(which is the number of pots she must make to get the same amount of money.
1344=16×4×x
1344=64x
1344/64=64x/64
21=x
For this case we must resolve the following expression:![log_ {0.5} (16)](https://tex.z-dn.net/?f=log_%20%7B0.5%7D%20%2816%29)
We have to:
![log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}](https://tex.z-dn.net/?f=log_%20%7Ba%7D%20%28x%29%20%3D%20%5Cfrac%20%7Blog_%20%7Bb%7D%20%28x%29%7D%20%7Blog_%20%7Bb%7D%20%28a%29%7D)
The base change rule can be used if a and b are greater than 1 and are not equal to x.
We substitute the values in the base change formula, using ![b = 10](https://tex.z-dn.net/?f=b%20%3D%2010)
![\frac {log (16)} {log (0.5)} = - 4](https://tex.z-dn.net/?f=%5Cfrac%20%7Blog%20%2816%29%7D%20%7Blog%20%280.5%29%7D%20%3D%20-%204)
Answer:
-4
Option A
At the end of practice, Joseph will need to run another 1.75 miles or 1 3/4 miles.
To determine this we need to subtract the amounts he already has run during practice from the goal of 3 miles.
3 miles - 1/2 miles - 1/4 miles - 1/4 miles - 1/4 miles = 1.75 miles
