Answer:
The sales tax in one state is 5%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $110.
A. f(x) = 5 + x; $111.05
B. f(x) = 0.05x; $5.50
C. f(x) = x � 5; $108.95
D. f(x) =1.05x; $115.50
total cost = (price) + (5% of price)
f(x) = x + 0.05x
f(x) = 1.05x
So the function is f(x) = 1.05x
Plug in x = 110 to get
f(x) = 1.05x
f(110) = 1.05*110
f(110) = 115.50
The item costs $115.50 (after tax is added on)
Step-by-step explanation:
1: the total cost of a CD player would be 104.76
2: Total Cost = (price) + (5% of price)
f(x) = x + 0.05x
f(x) = 1.05x
So the function is f(x) = 1.05x
Plug in x = 110 into the function
f(110) = 1.05*110
f(110) = 115.50
The item costs $115.50
3: Answer:
f(x) = .05x; $5.50
Step-by-step explanation:
f(x) = .05x
f(110) = .05(110) = $5.50

Answer:
- 16f - 12
Step-by-step explanation:
- 4(4f + 3) ← multiply each term in the parenthesis by - 4
= - 16f - 12
Complete question :
Select the two statements that are true about the equation y−10=60(x−40)
Answer:
m = 60
One point on the line is (40, 10)
Step-by-step explanation:
Given the equation :
y−10=60(x−40)
Comparing the equation with the point slope equation formula :
y - y1 = m(x - x1)
Where, x1 and y1 are points on the line
m = Slope
From here, we can deduce that:
y1 = 10 ; x1 = 40 and m = 60
(x1, y1) = (40, 10)
m = slope = 40
Answer:
11/100
here's your solution
Step-by-step explanation:
=> percent means divided by 100
=>. so. 11% =. 11/100
=>. 11/100
