The population of the study is the 30 bottles of mustard that were selected
"y varies directly as x" means y = kx
you do not know what k is yet, other than that it is some constant number.
Now plug in the given values, y=12 when x=4, in the equation
12 = 4k
=> k = 3
Now rewrite the equation with the k value you just found
y = 3k
Substitute 18 in place of x
y = 3(18)
y = 54
Answer:
140,000
Step-by-step explanation:
Take 400,000 * 0.35 = 140,000.
When given a percentage, take the number and divide by 100.
In this case 35 / 100 = 0.35.
Then you can take the total amount and multiply it by the percentage in decimal form.
In this case 400,000 * 0.35
