Answer:
$7.7
Step-by-step explanation:
Hello, I can help you with this
you can solve this by using a simple rule of three.
Step 1
define
if the wholesale price for a shirt is $5.50,it is 100 percent
$5.50⇔100%
the new price(x) is 40% more than the original, it means 140%
x ⇔ 140%
the relation is
Step 2
solve for x(isolate x)
the price of the shirt in the department store is $7.7
Have a nice day.
Answer:
Equation: y = -3x -2
Graph: Attached below ↓↓↓↓↓
Step-by-step explanation:
The equation is y = -3x + b
We need B at this point.
Since we have a point given to us,( -2, 4)we can input the x and y
Solve:
4 = -3(-2) + b
4 = 6 + b
b = -2
So the equation we have is y = -3x -2
Let's graph the line.
We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.

Convert minute to seconds (1 minute = 60 seconds), set up a proportion, cross multiply, and solve.
Proportion: =
Cross multiply: 60 · 100 = 5 · x
Solve (divide both sides by 5): 1200 = x
Answer: 1200 ft
