As per the direct variation formula, it take 11 hours : 6 minutes : 36 seconds to earn $25,000 for the restaurant.
Direct variation:
Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other.
Direct variation equation: y = kx
Given,
A local fast food restaurant takes in $9000 in a 4 hours period. Write a direct variation equation for the relationship income and number of hours.
Here we need to estimate how many hours it would take the restaurant to earn $25,000.
a) Let us consider income (I) directly varies to number of hours (h) where k is the constant of variation.
I = kh ⇒ Direct variation equation
Solve for k:
9,000 = (k)(4)
k = 9,000/4
k = 2,250
b) When income (I) = 25,000, find the number of hours:
I = kh
25,000 = (2,250) (h)
h = 25,000/2,250
h = 11.11
It will take approximately 11 hours : 6 minutes : 36 seconds for the restaurant to earn $25,000.

Find n, x, p and q
n always represent the population surveyed;
So:
x represents the sample from the population
So:
p always represents the given proportion
Solving for q
Answer:
or 1.945%
Step-by-step explanation:
Term annual percentage rate(APR) is the annual interest rate charged ona financial year for a duration of one year. APR can be converted to weekly, monthly, daily or even semi-annual rates using the below formula.
Effective rate for period = (1 + annual rate)(1 / n of periods) – 1
Rate is given as:
