Answer:
![A(t)=80(1.05)^t](https://tex.z-dn.net/?f=A%28t%29%3D80%281.05%29%5Et)
Step-by-step explanation:
The manufacturing plant earned $80 per man-hour of labor when it opened
The plant earns an additional 5% for every additional man-hour t.
This can be modeled using the function:
![A(t)=P(1+r)^t](https://tex.z-dn.net/?f=A%28t%29%3DP%281%2Br%29%5Et)
where Initial Amount Earned, P=80
Rate of Increase, r=5%=0.05
Therefore, the function that models the amount earned at any time t is:
![A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t](https://tex.z-dn.net/?f=A%28t%29%3D80%281%2B0.05%29%5Et%5C%5CA%28t%29%3D80%281.05%29%5Et)
Answer:
A
Step-by-step explanation:
X<Y means x is less than y-5 and you get A.
8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5
