Answer:
f(3)=3
Step-by-step explanation:
Plugin 3 for x, and simplify
f(x) =5(x)−12
f(3) =5(3)−12
=15−12
f(3)=3
Number of shirts a department store bought = 200
Cost price of 200 shirts = $5400
Cost price of 1 shirt :
Thus, the cost price of one shirt = $27
Price at which the department store sold each shirt = $30
Which means :
▪︎Cost price of shirt = $27
▪︎Selling price of shrit = $30
Since selling price is greater than cost price, there was a markup in the price of the shirts.
We know that :
Markup percentage in the price of the shirts :
Thus, the percentage of markup =
Therefore, the percentage of markup in the shirt's price =
Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.
<h3>What equation represents Sam's situation?</h3>
5.99 + x12.50 = 80.99
x represents the number of t-shirts she bough, which is the focus of the equation.
Let's solve it:
- 5.99 + x12.50 = 80.99
- x12.50 = 80.99 - 5.99
- x12.50 = 75
- x = 75 / 12.50
- x = 6
<h3>How many t-shirts did Sam order?</h3>
Sam ordered 6 t-shirts.

+6 both sides
16x=96
divided by 16 both sides to isolate x
x=6
