Question

If 2020 could not get any more unpredictable, there

has been a 50% increase of ghostly hauntings. Let'g
represent the number of typical hauntings and 'h'
represent the number of total new hauntings in 2020.
Which equations are correct? Select all that apply.

A. h = 1.5g
B. h=9+0.5
C. h = g +0.5t
D. h = g + 50
E. h= (1 + 0.5)g"

Answer 1

The correct equations that represent a 50% increase in ghostly hauntings are h = 1.5g and h = (1 + 0.5)g since they both correctly calculate the total number of new hauntings based on the original amount.

Step-by-step explanation:

If 2020 saw a 50% increase in ghostly hauntings, we're required to find the correct equations that represent the total number of new hauntings (h) based on the typical number of hauntings (g). To find an increase of 50% on the original amount, we multiply the original amount by 1.5 (which represents the original 100% plus the additional 50%).

Therefore, the correct equations that apply are:

1. h = 1.5g: This equation suggests that the total hauntings are 1.5 times the typical hauntings.
2. h = (1 + 0.5)g: This is another way of expressing that the total hauntings are the sum of the original amount plus 50% of it.

The other options are either incorrect due to their structure, like h = g + 0.5t which introduces an undefined variable t, or they simply do not accurately reflect a 50% increase as needed.
