Pavel [41]

<u>Answer-</u>

<em>The amount will be </em><em>$8944.62</em><em> after 5 years.</em>

<u>Solution-</u>

We know that,

\text{FV of annuity}=P[\dfrac{(1+r)^n-1}{r}]

Where,

P = Payment = $50 monthly

r = rate of interest compounded monthly= 3\frac{1}{4}=3.25\%=0.0325

n = number of period = 5 years = 5×12 = 60 months

Putting the values in the formula,

\text{FV of annuity}=50[\dfrac{(1+0.0325)^{60}-1}{0.0325}]

=50[\dfrac{(1.0325)^{60}-1}{0.0325}]

=50[\dfrac{6.8140-1}{0.0325}]

=50[\dfrac{5.8140}{0.0325}]

=50\times 178.8923

=8944.62

Therefore, the amount will be $8944.62 after 5 years.

Morgarella [4.7K]
<span>Last year, Shantell bought a car for 24 000 dollars. It decreases to 21 000 dollars this current year.
Let’s find for the percentage that it decreased.
=> in 24 000 the 50% is 12 000 as we all know since it’s divided by 2. So meaning, the possible answer is less than 50%.
=> now 25% of 24 000 is 6 000, and the amount that we’re looking is 3000, thus, the answer is 12.5%
=> 24 000 * 0.125 = 3000
=> 24 000 – 3000 = 21 000</span>

Determine sun or difference <br> -3 1/3 + 2 2/5
Artist 52 [7]

Answer:

-14/15

Step-by-step explanation:

First, you want to turn each mixed number into an improper fraction. So you get -10/3 + 12/5. Then you want to get the same denominator, and the LCD happens to be 15. You get -50/15 + 36/15. Addition is commutative, so you can do something like this: 36/15 - 50/15. You can do 36-50=-14, and then add the denominator to get -14/15.
