Answer:

The equation of this line would be y = -2x + 5

Step-by-step explanation:

To find any line given a slope and a point, use the base form of point-slope form and plug in the known values. Then solve for y.

y - y1 = m(x - x1)

y - 1 = -2(x - 2)

y - 1 = -2x + 4

y = -2x + 5

What is the store paid $75 for a clarinet and sold it for $100 did the store mark up the price by 30% what the answer
nevsk [136]

Answer:

Mark up  = 33.33%

Step-by-step explanation:

Given that:

buying price = $75

selling price = $100

First we will find the difference between two prices:

Difference = 100 - 75 = $25

We will find now that 25 is what percent of 75 so:

=25/75* 100

=  0.333333 * 100

= 33.33%

So the store marked the price by 33.33% instead of 30%

i hope it will help you!
