Answer:
B. 3b -0.51b
Step-by-step explanation:
The factor outside parentheses multiplies each term inside parentheses.
3(b -0.17b) = 3(b) +3(-0.17b) = 3b -0.51b . . . . note the minus sign
The term 3b represents the original price of 3 loaves of bread.
The term -0.51b represents the total discount on the price of 3 loaves of bread.
Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
when ![x = 0](https://tex.z-dn.net/?f=x%20%3D%200)
For bacteria B, we have:
![B(x) = 500(2)^x](https://tex.z-dn.net/?f=B%28x%29%20%3D%20500%282%29%5Ex)
Substitute 0 for x
![B(x) = 500(2)^0](https://tex.z-dn.net/?f=B%28x%29%20%3D%20500%282%29%5E0)
![B(x) = 500*1](https://tex.z-dn.net/?f=B%28x%29%20%3D%20500%2A1)
![B(x) = 500](https://tex.z-dn.net/?f=B%28x%29%20%3D%20500)
So; when x = 0
and ![B(x) = 500](https://tex.z-dn.net/?f=B%28x%29%20%3D%20500)
Because; 500 < 600
We can conclude that B has a smaller initial population of 500
12-5=7, and 7times 5 is 35 so Meena needs to make at least 8 pies to make a profit which would be $5
