2. The cafeteria sold cookies as
part of a fundraiser. Out of all
the cookies sold, 1/3 were peanut
butter and 3/6 were chocolate
chip. What fraction represents
how many more chocolate chip
cookies were sold than peanut
butter?

To solve this problem, we can set up a system of equations. Let's let the variable p represent the number of peanut butter cookies that were sold and the variable c represent the number of chocolate chip cookies that were sold. Using our given information, we know that the number of chocolate chip cookies must be half the number of peanut butter cookies, or 1/2p = c. Because there are 12 cookies in a dozen and twenty dozen cookies were sold total, we know that the sum of the chocolate chip and peanut butter cookies must equal twenty dozen, or p + c = 20(12). So, our system of equations is:

1/2p = c

p + c = 20(12)

To solve, we can substitute the value for c in terms of p given by the first equation into the second equation for the variable c, and then solve for p. This is shown below:

p + c = 20(12)

p + 1/2p = 20(12)

To simplify, we should compute the addition on the left side of the equation and the multiplication on the right side of the equation, which gives us:

1 1/2p = 240

To solve for p, we must get this variable alone. To do this, we should divide both sides of the equation by 1 1/2.

p = 160

Now, we can substitute this value for p into one of our original equations to solve for c:

1/2p = c

1/2(160) = c

To solve, we just multiply the two factors on the left side of the equation together.

c = 80

Therefore, your answer is that 160 peanut butter cookies were sold and 80 chocolate chip cookies were sold.

the answer is a.

135 and 80

step-by-step explanation:

explanation:

the loan estimate encourages consumers to shop. since it is the lenders who are required to issue a standardized loan estimate in a specific time frame, this way consumers are provided an opportunity to compare lenders and their products. otherwise consumer wouldn't know the benefits offered by other lenders.  

if a loan originator does not provide a loan estimate within 3 business days of receiving a completed loan application, that lender is in violation. lenders are required to issue a loan estimate within 3 days of applying for a loan or within 7 days prior to closing. having a loan estimate has following information.

not having loan estimate won't give you an idea of money to be borrowed.

you get to know your interest rates.

you also get to know if your interest rate can or may vary.

not having a good faith estimate can keep you unaware of aforementioned points.
