Carolina receives an allowance that is tied to completing her chores during the week. She starts off with an allowance of $20. She has five chores to complete during the week, and for each chore she completes, she receives $3. However, for each chore that is not done by the end of the week, she loses $4 from her allowance. a. Write an expression describing Carolina's allowance as a function of the number of chores, C, that she completes during the week.

b. If Carolina completes 4 chores, what is her allowance?

a. x = 7c

b. $28

Step-by-step explanation:

Her allowance starts at $20.

Out of 5 chores, for each chore she completes, she receives $3.

For each chore that she does not complete, she loses $4.

a. An expression describing her allowance

Let her total allowance be x:

x = 20 + (3 * c) + (-4 * (5 - c))

x = 20 + 3c - 20 + 4c

x = 20 - 20 + 7c

x = 7c

b. If she completes 4 chores, she will receive:

x = 7 * 4 = $28

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
