A survey was done that asked people to indicate whether they preferred pool swimming or ocean swimming. The results of the survey are shown in the two-way table. Chantal is making a relative frequency table from this data.

What operation should Chantal perform to determine the relative frequency of a person over 30 years old who prefers ocean swimming?

step-by-step explanation:

sry but any answer choices

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

to determine the unit cost your would divide the total cost by the number sold.
