The cost of a stove to a store owner was $500, and she sold the stove for $1080. What was her percent of profit based on cost?

Juliette [100K]

Answer:

116%

Step-by-step explanation:

Cost Price (C. P.) = $500

Selling Price (S. P.) = $1080

Profit = SP - CP = $1080 - $500 = $580

Profit percent

$= \frac{Profit}{CP} \times 100 \\ \\ = \frac{580}{500} \times 100 \\ \\ = \frac{580}{5} \\ \\ = 116 \%$

Find the slope of the line that passes through the points (0,-11) and (8,-8).

Korolek [52]

To find the slope of a line, we can use the following formula:

$\displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }$

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

$\displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}$

Substitute the points in formula:

$\displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }$

Negative multiply negative always come out as positive.

$\displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\$

Since m stands for slope, we can say that:

$\displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}$
