Answer:
Mrs. Cook has to grade 63 tests.
Step-by-step explanation:
In order to find the answer, first you have to calculate 80% of the number of tests Ms. Morris has:
35*80%= 28
Then, you have to add the number that represents 80% to the number of tests Ms. Morris has to grade:
35+28=63
According to this, the answer is that Mrs. Cook has to grade 63 tests.
Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
<h3>What is an exponential function?</h3>
It is modeled by:

In which:
- a is the initial value, that is, y when x = 0.
- b is the rate of change, as a decimal.
Function 1 is given by:

Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:

Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

177 + s < = 0.20(1000)....where s = weight of the camping supplies
177 + s < = 200
s < = 200 - 177
s < = 23 <== so, at most, his camping supplies can weigh 23 lbs
