Use the following compound interest formula to complete the problem. a = p (1 startfraction r over n endfraction) superscript n
Ratling [72]

The final amount that Victor will owe after one year, to the nearest cent is given by: Option C: $545.65

<h3>How to find the compound interest?</h3>

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

a = p(1 + \dfrac{r}{n})^{nt}

For this case, we're provided that:

The interest rate is r = 13.66% = 13.66/100 = 0.1366 (converted percent to decimal)

It is compounding monthly, thus, 12 times a year, or n = 12

The initial amount that the credit card of Victor has = p = $1349.34

Time for which interest was compounded = a year = 1 = t

Thus, the final amount that Victor will owe after one year to the nearest cent is calculated as;

a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 1349.34(1 + \dfrac{0.1366}{12})^{12\times 1}\\\\a = 1349.34(1.01138)^{12} \approx 1245.65 \: \rm (in \: dollars)

Thus, the final amount that Victor will owe after one year, to the nearest cent is given by: Option C: $545.65

So, I'm in 9th grade. We are learning slope, but I don't understand. Does anyone have a simple method that they could explain to
Mazyrski [523]
I always used rise over run. which is when you count up the y axis for run and count over on the x axis for the run. then take your rise over run and there is your slope.
