Answer:
a) price markup $0.60
b) percent marked up 180%
Step-by-step explanation:
Amount marked up:
1.35 - 0.75 = $0.60
Percent markup:
0.75x = 1.35
x = 1.8 or 180%
Answer:
x = 
or

Answer:
<u>The correct answer is A. - 11 square root of 7.</u>
Step-by-step explanation:
We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.
Let's simplify it:
2 √28 - 5 √ 63
2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)
2 * 2 √7 - 5 * 3 √ 7
4 √7 - 15 √7
- 11 √7
<u>The equal expression is A. - 11 square root of 7.</u>
Yosef should have multiplied the x-values by 80 to get the y-values.
<h3>Functions and tables</h3>
Tables are told used to arrange ungrouped data.
From the given table, we can find the equation by using the coordinate points (1, 80) and (1, 160)
<h3>Find the equation of the line</h3>
The standard equation of a line is y = mx + b
m is the slope
b is the y-intercept
Slop = 160-80/2-1
Slope = 80
For the y-intercept
160 = 80(2) + b
b = 0
The required equation is y = 80x
This means that Yosef should have multiplied the x-values by 80 to get the y-values.
