Answer:

B (for question 7)

Step-by-step explanation:

To find the slope, we use the equation m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }.

m = (-4+1)/(7+2) = -3/9 = -1/3

Since B is the only option that would give a slope of -1/3, B must be the answer.

(you can use this same method for question 8)

You buy items costing $1900 and finance the cost with a fixed installment loan for 24 months at 8% simple interest per year.
ddd [48]

9514 1404 393

Answer:

  1. $304
  2. $91.83

Step-by-step explanation:

1. The finance charge is found from the simple interest formula;

  I = Prt

where P is the principal amount, r is the annual rate, and t is the number of years.

24 months is 2 years, so the interest charged is ...

  I = $1900×0.08×2 = $304

The finance charge is $304.

__

2. The monthly payment will be the total amount due, divided by the number of months.

  payment = ($1900 +304)/24 = $2204/24 ≈ $91.83

The monthly payment is $91.83.
