Simplify the equation 28st/-4t

Mathematics
1 answer:
Gnoma [55]3 years ago
7 0

We can simplify both the numeric and literal parts.

It could be useful to rewrite the fraction as follows, to make clear what we're simplifying with what:

\dfrac{28st}{-4t} = -\dfrac{7\cdot 4}{4}\cdot s \cdot \dfrac{t}{t}= -7\dfrac{4}{4}\cdot s \cdot \dfrac{t}{t}

The fractions 4/4 and t/t simplify to 1, since the numerator and denominator are the same. So, we're left with

\dfrac{28st}{-4t} =-7s

Cloud [144]

Answer:

Determination of the Finance Charge, Carry-over balance, Minimum Payment for each of the next two months:

Finance Charge:

First month = $7.91

Second month = $7.72

Carry-over balance:

First month = $487.59

Second month = $475.50

Minimum Payment:

First month = $20.32

Second month = $19.81

Starting balance (Carry-over balance + Finance charge):

First month = $507.91

Second month = $495.31

Step-by-step explanation:

a) Data and Calculations:

Credit Finance = $500

APR = 18.99%

Minimum monthly payment = 4% of the balance

Monthly rate of interest = 0.1899/12 = 0.015825

Finance Charge:

First month = $7.91 ($500 * 0.015825)

Second month = $7.72 ($487.59 * 0.015825)

Carry-over balance:

First month = $487.59($507.91 - $20.32)

Second month = $475.50 ($495.31 - $19.81)

Minimum Payment:

First month = $20.32 ($507.91 * 4%)

Second month = $19.81 ($495.31 * 4%)

Starting balance (Carry-over balance + Finance charge):

First month = $507.91 ($500 + $7.91)

Second month = $495.31 ($487.59 + $7.72)
