Answer: - 33

Step-by-step explanation:

Since, the speed of scuba diver = 2.5 feet  per second

Thus, the distance covered by her in 7 second = 2.5 × 7 = 17.5 feet

But, According to the question,

She is 15.5 feet below the surface of water when she start swimming.

Thus, her total distance from the surface of water after 7 second

= Her distance from the surface when she start + the distance cover by her in 7 second

= 15.5 + 17.5 = 33 feet.    

Thus, -33 represents her location relative to the surface after 7 seconds when we take surface as x-axis.

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.
