Answer:

The total amount Arnold pay in interest is $ 2521.30

Step-by-step explanation:

Given :Arnold borrowed $7890 at 11.5 percent for five years.

We have to find the amount Arnold pay in interest

Using formula for monthly payment ,

Monthly\ payment = \frac{rate \times Principal}{1-(1+rate)^{-time\ period}}

Given :  Principal value = $7890

Rate of interest = 11.5% anually

So monthly interest rate is \frac{11.5}{1200}

Time = 5 years

In months 5 years = 5 ×  12 = 60 month

Substitute, above we have,

Monthly\ payment=7890\cdot\frac{\frac{11.5}{1200}}{\left(1-\left(1+\frac{11.5}{1200}\right)^{-60}\right)}

Simplify, we get,

Monthly payment = $ 173.52

Total payment that Arnold pay = No. of months × Monthly Payment

⇒ Total Payment = 60 × 173.52

⇒ Total Payment =  $ 10411.30

Since, Money Arnold borrowed = $7890

Thus, Amount of interest = Total payment - Amount borrowed

⇒ Interest = 10411.30 - 7890

⇒ Interest = $2521.30

Thus, The total amount Arnold pay in interest is $ 2521.30

Paga No. Date: 6. When a discount of 25% is allowed on the marked price then the selling price will be 1425 .lf the marked price
SVETLANKA909090 [29]

Answer:

The percentage loss = 10.9375 %

Step-by-step explanation:

Let the cost price = x

Since the marked price is 18.75% above the cost price so the

Marked price = 1.1875 x

When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425

⇒ Marked price × 0.75 = 1425

⇒ Cost price × ( 1.1875 × 0.75 ) = 1425

⇒ Cost price × ( 0.890625 ) = 1425

⇒ Cost price = 1600

Selling price = 1425

So percentage loss =  × 100

% Loss =  × 100

% Loss = 10.9375 %

HELPPPPPPPP!!!!!!!!!!
Novosadov [1.4K]

Step-by-step explanation:

98 = 188t - 16t^2

-16t^2 + 188t = 98

-16t^2 + 188t - 98 = 0

8t^2 - 94t + 49 = 0

Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions

t = [(47 - root 1817) / 8]≈ 0.55

and

t = [(47 + root 1817) / 8] ≈ 11.20
