Solve the following problem. PV=$24,122; n = 70; i = 0.024; PMT ?; PMT = $ (Round to two decimal places.)
Ira Lisetskai [31]

Answer:

The payment per period is $714.82.

Step-by-step explanation:

Given information: PV=$24,122; n = 70; i = 0.024

The formula for payment per period is

PMT=\frac{PV\times i}{1-(1+i)^{-n}}

Substitute PV=$24,122; n = 70; i = 0.024 in the above formula.

PMT=\frac{24122\times 0.024}{1-(1+0.024)^{-70}}

PMT=\frac{578.928}{0.80989084337}

PMT=714.822256282

PMT\approx 714.82

Therefore the payment per period is $714.82.

Blairs new computer cost 5$ less than twice the cost og her old computer. Her new computer cost 709$. how much did blairs old co
Phantasy [73]

The cost of old computer is $ 357

<em><u>Solution:</u></em>

Let "x" be the cost of old computer

From given,

Cost of new computer = $ 709

Blairs new computer cost 5$ less than twice the cost of her old computer

Therefore,

Cost of new computer = twice the cost of old computer - 5

Cost of new computer = 2x - 5

709 = 2x - 5

2x = 709 + 5

2x = 714

Divide both sides by 2

x = 357

Thus the cost of old computer is $ 357
