Answer:
20 miles
Step-by-step explanation:
Given the equation of the line of the graph, y = 8x, where,
y = distance the hurricane travelled in miles
x = time of travel in hours
8 = slope/speed in miles/hour
To find how far the hurricane travelled in 2.5 hours, substitute x = 2.5 into y = 8x
This:
y = 8(2.5)
y = 20 miles
Thus, from the graph, we can estimate this also. On the x-axis, between 2 and 3, we have 2.5 hours. The corresponding value of x = 2.5 is y = 20.
Answer:
- y = 1.5x
- y = 15 when x = 10
Step-by-step explanation:
A direct variation equation is of the form ...
y = kx
for some constant k. We can arbitrarily choose k=1.5, so our equation is ...
y = 1.5x
For x=10, the value of y is ...
y = 1.5·10 = 15
Markup is the amount a certain seller is adding to the cost to get the selling price of her product. In this problem, Camille Keegan has the selling price of $92.10 and the cost is $62.00. To get the markup, you just have to deduct the cost from the selling price:
$92.10 - $62.00 = $30.10
To get the percent markup, you just have to divide the
markup by the cost of the product:
$30.10/$62.00 = 48.55% markup
