The natural market sells a 12-ounce jar of peanut butter for $3.96. They also sell bulk peanut butter for $5.50 per pound. The _
patriot [66]

Answer:

The Jar of peanut butter

Step-by-step explanation:

The easiest way to do this is to calculate price per ounce of each unit.

We'll assign the 12 ounce jar to the variable s and the bulk to the variable b.

First create an equation to find the values of each product per ounce.

Since the 12 ounce jar(s) sells for 3.96 we can say it is 3.96 for every 12 ounces, or s = 3.96/12oz.

Simplify this equation and you get s = 0.33 per ounce.

For b we need to convert pounds to ounces.

There are 16 ounces per pound so the equation we get is:

b = 5.50/16oz

Simplified we get:

b =  about 0.34/oz

The smaller jar has a rate of $0.33/oz

The bulk has a rate of $0.34/oz

This means the answer is b. The jar of peanut butter has a cheaper unit rate.

Jamie purchased a condo in Naples, Florida, for $699,000. She put 20% down and financed the rest at 5% for 35 years. What are Ja
EleoNora [17]
The payments are ...
  A = P(r/n)/(1 -(1+r/n)^(-nt))
where P is the principal amount, $699,000*0.80 = $559,200
  r is the annual interest rate, 0.05
  n is the number of compoundings per year, 12
  t is the number of years.
Then
  A = 559,200*(0.05/12)/(1 -(1 +0.05/12)^(-12*35)) = 2822.21

The total of 420 of these payments is $1,185,328.20, which is $626,128.20 more than the loan amount.

Jamie's total finance charge is about $626,128.20.


_____
There is always some minor adustment required in the amount of the last payment. That has not been taken into account here.
