old selling price = $170
new selling price = $159.12

Explanation:
Part (a) getting old selling price:
The equation to get the selling price is given as follows:
selling price = original cost + markup value

We are given that:
original cost = $136
markup value = 25% = 25% * 136 = 0.25 * 136 = $34

Substitute in the equation to get the old selling price as follows:
old selling price = 136 + 34 = $170

Part (b): getting the new selling price:
The equation to get the selling price is given as follows:
selling price = original cost + markup value

We are given that:
original cost = $136
markup value = 17% = 17% * 136 = 0.17 * 136 = $23.12

Substitute in the equation to get the old selling price as follows:
old selling price = 136 + 23.12 = $159.12

Hope this helps :)

old price was $170; new price is $159.12

Step-by-step explanation:

If you take 136 and multiply it by 1.25, which includes the 25 percent markup you get $170 for the old price. Then if you take 136 and multiply it by 1.17, which includes the 17 percent markup, you get $159.12. so the answer is; C. old price was $170; new price is $159.12

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2 is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes. our only condition is that it passes through the point (-2,5)

A. write an equation of a line that passes through (-2, 5). b. how many different equations could y
