Answer:
42.8%
Step-by-step explanation:
Step one:
given data
A department store buys 100 shirts at a cost of $700
let us find the cost of 1 shirt
cost of 1 shirt= 700/100= $7 per shirt
The cost price per shirt = $7
We are given that the selling price = $10 per shirt
Step two:
The percent markup can be found as
percent markup= selling-cost price/cost price*100
percent markup= 10-7/10*100
percent markup= 3/7*100
percent markup= 0.428*100
percent markup= 42.8%
Gillian earned $42.75 total. On Saturday (2.2 hours * 7.50 per hour) she earned $16.50. On Sunday (3.5 hours * 7.50 per hour) she earned $26.25. $26.25 + $16.50 = $42.75.
Answer:
1). Increases
2). Slope = 4
3). Slope = -1
4). y = 4 when x = 5
Step-by-step explanation:
1). Initially, as x increases, y also increases. (Linear growth has been shown in the graph initially).
2). Afterward, the slope of the graph of the function is equal to 4 for all x between x = 3 and x = 5.
[Slope of the line passing through two points (3, 0) and (5, 4)
m = 
= 
= 
= 4 ]
3). The slope of the graph is equal to -1 for x between x = 5 and x = 9.
[Slope of the line passing through two points (5, 4) and (9, 0),
Slope = 
= 
= -
= -1 ]
4). The greatest value of y is y = 4, and it occurs when x = 5. (From the given graph)
Answer:
C
Step-by-step explanation:
B can immediately be eliminated because it has an area of 14.
A and C have an area of 10.
So add the sides.
C:
4 + 4 + 1 + 1 + 2 + 2 + 1 + 3
= 18
A: 3 + 3 + 2 + 2 + 1 + 1 + 1 + 1 =
10 + 4 =
14
