Mitchell took out a loan for $1100 at a 19.2% APR, compounded monthly, to
nevsk [136]

Answer:

The total number of the payments is 18 ⇒ answer A

Step-by-step explanation:

* Lets revise the rule of compounded monthly payment

→ EMI=\frac{(A)(r)}{[1-\frac{1}{(1+r)^{n}}]}, where

- A is the loan amount

- r is monthly interest in decimal (R/12*100))

- n the total number of payments

∵ A = $1100

∵ EMI = $71.5

- Interest rate is 19.2% APR

∵ r = \frac{19.2}{12*100}=0.016

- Substitute these values in the rule to find n

∴ 71.5 = \frac{1100(0.016)}{[1-\frac{1}{(1+0.016)^{n}}]}=\frac{17.6}{[1-\frac{1}{(1.016)^{n}}]}

- By using cross multiplication

∴ 71.5[1 - \frac{1}{(1.016)^{n}} ] = 17.6

- Divide both sides by 71.5

∴ 1 - \frac{1}{(1.016)^{n}} = \frac{16}{65}

- Subtract 1 from both sides

∴ - \frac{1}{(1.016)^{n}} = - \frac{49}{65}

- Multiply both sides by -1

∴ \frac{1}{(1.016)^{n}} = \frac{49}{65}

- By using cross multiplication

∴ 49[ (1.016)^{n} ] = 65

- Divide both sides by 49

∴ (1.016)^{n} = \frac{65}{49}

- Insert log for both sides

∴ ㏒ (1.016)^{n} = log( \frac{65}{49} )

- Put n in-front of the ㏒

∴ n㏒(1.016) = ㏒( \frac{65}{49} )

- Divide both sides by ㏒(1.016)

∴ n = 17.8 ≅ 18

* <em>The total number of the payments is 18</em>

How to find a slope
exis [7]

Answer:

Step-by-step explanation:

y₂₋y₁ / x₂-x₁   if you have two points you can plug them in and find the slope using this.

If it is on a graph you can look at two points and count the rise over run, for example if one point is (0, 0) and another is (2, 3) then from the first point it goes up 2 and over 3, so the slope would be 2/3
