You have a job which pays double-time when working more than 40 hours for a week. Last week you worked 55 hours and earned $840. What is your regular pay rate?​

$12/hour

Step-by-step explanation:

f(x) = px for x ≤ 40 hours

f(x) = px + 2py if you do overtime work

y = the over time

p = regular pay

840 = 40p + 2(15)p

840 = 40p + 30p

840 = 70p

p = 840/70 = $ 12/hour

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

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.
