Atoy store marks up every toy by 15% in january. how much does a toy cost during january? use p for the price in december

D   1.15p

Step-by-step explanation:

Since the price is marked up 15%, you add 15% to the original price, which is p.

15% = .15

p = 1p

1p + .15p = 1.15 p

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
