Answer: "Three times the sum of 8 and 4":
Explanation:
In the question we have asked that what will be the mathematical expression for the " three times the sum of 8 and 4".
We have asked with 'Three times the sum of 8 and 4' which means that adding the sum of number '8' and number '4' by three times.
We can write 'Three times the sum' mathematically as '3 '.
We can write 'sum of 8 and 4' mathematically as '
So the final expression comes out to be:

To find the equation of the graph, what we do is to recognize some characteristics of a sine function:
- Amplitude: The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In this case, the amplitude is 1.
- Period: The period of a sine function is defined as the length of one complete sine wave or one complete cycle of the curve. It can be found using the equation: P=2pi/B.
Why are these characteristics important?
Because the sine function has the following general form:
In this problem, we have A=1 and we know that the period equals 2pi/3. So,
Therefore, the equation of the graph is:
Answer:
You can sell at least 40 phones each week.
Step-by-step explanation:
Given that:
Weekly base salary = $150
Earning on each phone = $20
Maximum amount that can be earned each week = $950
Let,
m be the number of phones.
20m + 150 ≤ 950
20m ≤ 950 - 150
20m ≤ 800
Dividing both sides by 20
m ≤ 40
Hence,
You can sell at least 40 phones each week.
