The average price of a gallon of milk is $3.31. If the price increases .88% each year , how much will a gallon of milk cost in 20 years?

$3.94

Step-by-step explanation:

You will need to use the compound interest formula for this.

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Your equation will look like this:

= 3.94

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
