71/20 is not in simplest form because you need to change it into a mixed number by dividing 71 and 20 and putting the remainder over 20.
We have been given that a store manager paid $95 for an item and set the selling price at $116.85. We are asked to find the percent mark-up.
We will use percent increase formula to solve our given problem.
Therefore, the mark-up will be 23% and option 'b' is the correct choice.

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x - 2
g(x) = x² - 5
<u>Step 2: Find g(f(2))</u>
f(2)
- Substitute in <em>x</em>: f(2) = 3(2) - 2
- Multiply: f(2) = 6 - 2
- Subtract: f(2) = 4
g(f(2))
- Substitute in <em>x</em>: g(4) = 4² - 5
- Exponents: g(4) = 16 - 5
- Subtract: g(4) = 11
Answer:
∠B = 12°
∠C = 180 - 48° = 132° ( straight line angle = 180)
Sum of angles of a triangle = 180°
180 = ∠A + ∠B + ∠C
180 = ∠A + 12 + 132
180 - 144 = ∠A
∠A = 36°
option B
Using the scatter plot, it is found that 4 visitors were there during the fourth hour.
<h3>What is a scatter plot?</h3>
- A scatter plot is similar to a function graph, as for each value of x, it will have the corresponding value of y.
Researching the problem in the internet, it is found that:
- The values of x represents each hour.
- The corresponding y-value represents the number of visitors during hour x.
- In the plot, we have that when x = 4, y = 4, hence, 4 visitors were there during the fourth hour.
