Chip and Joanna Gains purchase a house for $40,000. After renovations, they sell the house for $240,000! What is the percent increase of the value of the home?

600%

Step-by-step explanation:

Set up a ratio

40,000/240,000 = 100/x

40,000x = 24,000,000

x = 600%

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
