A family is purchasing a house and needs to finance a 195,000 mortgage from the bank with an annual percentage rate (APR) of 5.3

maksim [4K]

Calculate the monthly payment:

195,000 x ( (0.05/12)x1+0.053)^12)/(1+0.053)^12-1)

Monthly payment = 1,082.84

Multiply monthly payment by 12 to get one year: 1082.84x 12 = 12994.08

Now multiply by 30 years:

12994.08 x 30 = 389822.40

The answer is $389,822

How do I factor the quadratic equation

anastassius [24]

Factor the following:
10 y^2 - 35 y + 30
Factor 5 out of 10 y^2 - 35 y + 30:
5 (2 y^2 - 7 y + 6)
Factor the quadratic 2 y^2 - 7 y + 6.
The coefficient of y^2 is 2 and the constant term is 6.
The product of 2 and 6 is 12.
The factors of 12 which sum to -7 are -3 and -4. So 2 y^2 - 7 y + 6 = 2 y^2 - 4 y - 3 y + 6 = y (2 y - 3) - 2 (2 y - 3):
5 y (2 y - 3) - 2 (2 y - 3)
Factor 2 y - 3 from y (2 y - 3) - 2 (2 y - 3):
Answer: 5 (2 y - 3) (y - 2)

Annual fixed costs for a product are $75,000. The product itself sells for $6 and it costs $2 in variable costs to make each pro

rusak2 [61]

Given

Annual fixed costs for a product are $75,000.

The product i sells for $6

it costs $2 in variable costs to make each product.

the variable cost per unit goes up to $2.50

find out how many units will the annual break-even point for the product change .

To proof

FORMULA

Break even = Fixed cost ÷ Contribution margin per unit

where

Contribution margin per unit = sale price - variable price

Take two cases

Case first

fixed costs for a product = $75,000

product itself sells = $6

variable costs = $2

put all the value in the above equation

we get

Contribution margin per unit = 6 - 2

= 4

$Break even (say B1 ) = \frac{75000}{4}$

= 18750 units

CASE SECOND

the variable cost per unit goes up to $2.50

put value inthe formula

Contribution margin per unit = 6 - 2.50

= 3.5

$Break even (say B2 ) = \frac{75000}{3.5}$

we get

Breakeven (sayB2) = 21428.6 unit

change in the break even product = B2- B1

= 21428.6 - 18750

= 2678.6 unit

Hence proved
