djverab [1.8K]

Answer:

$415.18

Explanation:

The calculation of the present value of a cash flow or other income stream that produces $1 in income over so many periods of time.

DATA

Amount borrowed = $12,500

Annual interest rate = 12.00%

Monthly interest rate = 1.00%

Period = 36 months

Let monthly payment be x

12,500 = x/1.01 + x/1.01^2 + x/1.01^3 … + x/1.01^35 + x/1.01^36

12,500 = x * (1 - (1/1.01)^36) / 0.01

12,500 = x * 30.107505

x = 12,500/30.107505

x = 415.18

The monthly payment is $415.18

Three consecutive integers are n, n+1, and n+2.

Vera_Pavlovna [14]

We convert the sentences to mathematical expressions as follows

"Four times the sum of the least and greatest integers" : 4[n+(n+2)]

"is 12 less than three times the least integer": = 3n-12

So we have:

4[n+(n+2)]=3n-12 (this is the equation)

4[2n+2]=3n-12
8n+8=3n-12

8n-3n=-12-8
5n=-20

n=-20/5=-4

Answer: the equation is 4[n+(n+2)]=3n-12 , the least integer is -4

Answer:

Option A is the correct choice.

Step-by-step explanation:

We have been given the system of linear equations written by Draco. We are asked to find Draco's error.

Let us form a system of equations using our given information.

Let m represent the price of one muffin and b represent the cost of one bagel.

We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:

$5m+9b=25.50...(1)$
