He spends 272 dollars total. That includes 1/4 + 3/5 of his monthly budget.
Which means:
(1/4 + 3/5) * monthly budget = 272 dollars
solving the equation gets you:
monthly budget = 320 dollars

Answer:
The surface area of the paperweight is 
Step-by-step explanation:
we know that
The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces
so
<em>Find the area of its triangular base</em>


<em>Find the area of its three triangular lateral faces</em>
![SA=3[\frac{1}{2}(2)(2.2)]](https://tex.z-dn.net/?f=SA%3D3%5B%5Cfrac%7B1%7D%7B2%7D%282%29%282.2%29%5D)

Adds the areas


A. 6n - 2
b. 5 - 9/n
c. 1/2(6n/22)
d. 9 - 2(n - 7)
e. 11 - n to the second power
Using it's concept, it is found that the average rate of change of this function over the interval of time from 30 days to 60 days is of 0.4 insects per day.
<h3>What is the average rate of change?</h3>
- The <em>average rate of change</em> of a function f(x) over an interval [a,b] is given by the <u>change in the output divided by the change in the input</u>, that is:

In this problem:
- The inputs are of 30 and 60 days, hence
.
- At day 30, there are 20 insects, hence
.
- At day 60, there are 32 insects, hence
.
Then:

The average rate of change of this function over the interval of time from 30 days to 60 days is of 0.4 insects per day.
