If the sale tax rate is 8.75% in New York State, how much sales tax would you pay for a $35 pair of pants? And at Best Buy they

bogdanovich [222]

The pants are $38.06 and the television is $1,147.50.

The sales tax on the pair of pants is calculated by multiplying $35 x .0875 = $3.06

The total cost is $35 + 3.06 = $38.06.

The sales price of the television is calculated by multiplying $1,250 x .85, (100 - .15 discount = .85) = $1,062.50 is the sales price

The sales tax is calculated by multiplying $1,062.50 x .08 = $85

The total price is $85 + $1,062.50 = $1,147.50

John takes out a loan for $ 10 , 000 at a simple interest rate of 5 % to be paid back in 36 monthly installments.

andrew-mc [135]

The monthly principal and interest payment John will pay monthly is $3,750.04

<h3>What is the amount of principal and interest repayment?</h3><h3 />

Given:

P = 10,000
i = 5% / (12 months) = 0.375
L = 36 months

$M = 10000 \times \frac{0.375}{ {1 - (1 + 0.375)}^{ - 36} }$

$M = 10000 \times \frac{0.375}{ {1 - (1.375)}^{ - 36} }$

$M = 10000 \times \frac{0.375}{ {1 - (0.00001049791)} }$

$M = 10000 \times \frac{0.375}{ 0.99998950208 }$

$M = 10000 \times 0.37500393675$

$M = 3750.03936758$

Approximately,

M = $3,750.04

Therefore, John will be be repaying $3,750.04 monthly including principal and interest
