Answer:
The store will sell the guitar for $58.50
Step-by-step explanation:
$45 * 1.3 = $58.50
Since the price they bought it for is $45 and the markup percent is 30%, we multiply $45 by 1.3, which will give us $58.50.
Answer:
C
Step-by-step explanation:
Area of triangle: 1/2(base)(height)
Area of rectangle: length × width
Find the area of the triangles on the sides first using 1/2(base)(height).
Plug 8 for the base and 6 for the height.
1/2(8)(6) = 24 units²
Multiply 24 by 2 for both of the triangles.
(24)(2) = 48 units²
Find the area of the rectangles of the object using length × width.
For the rectangle on top, you can find the width using the Pythagorean Theorem: a² + b² = c².
Plug in 6 and 8 for a and b, and find c (width).
6² + 8² = c²
36 + 64 = 100
Square root both sides; √100 = 10.
The width of the rectangle on top is 10.
Now plug 20 for the length and 10 for the width.
20 × 10 = 200 units²
For the rectangle on the bottom, plug in 20 for the length and 8 for the width.
20 × 8 = 160 units²
For the rectangle on the side, plug in 20 for the length and 6 for the width.
20 × 6 = 120 units²
Add up all the areas ⇒ 48 + 200 + 160 + 120 = 528 units².
Answer:
Step-by-step explanation:
a). Since starting point of the line is (0, 50),
Therefore, I started with the saving of $50.
b). Since endpoint of the segment is (5, 175),
Money with me after 5 weeks will be $175.
c). Let the equation of the line given in the graph is,
y - y' = m(x - x')
Where (x', y') is a point lying on the graph.
And 'm' is the slope of the line.
Slope of the line = 
m = 
m = 25
Since, the line passes through (0, 50),
y - 50 = 25(x - 0)
y = 25x + 50
y = 25x + 50
For x = 6,
y = 25×6 + 50 = 200
For x = 7,
y = 25×7 + 50 = 225
For x = 8,
y = 25×8 + 50 =250
d). For x = 10 weeks,
y = 25×10 + 50 = $300
e). For x = 15 weeks
y = 25×15 + 50 = $425
f). For x = 50 weeks,
y = 25×50 + 50 = $1300
g). Equation of the line is,
y = 25x + 50
