The library gets 2625 dollars. If gift cards are 15 dollars and they sell 500 then they made 7,500 dollars and 35% of that is 2625 dollars
Answer:
<em>The correct option is: B. $30.00</em>
Step-by-step explanation:
<u>The formula for compound interest</u> is.......
, where A= Final amount, P= Initial amount, r= rate of interest in decimal form, n= number of compounding in a year and t= time duration in years.
Anthony wants to buy CD for $400 that earns 2.5% APR and is compound quarterly and the CD matures in 3 years.
So here, ![P= 400, r=2.5\%=0.025, t= 3](https://tex.z-dn.net/?f=P%3D%20400%2C%20r%3D2.5%5C%25%3D0.025%2C%20t%3D%203)
As the CD is compounded quarterly, so here ![n= 4](https://tex.z-dn.net/?f=n%3D%204)
Plugging these values into the above formula......
![A= 400(1+\frac{0.025}{4})^(^4^*^3^)\\ \\ A= 400(1+0.00625)^1^2\\ \\ A=400(1.00625)^1^2\\ \\ A= 431.053...](https://tex.z-dn.net/?f=A%3D%20400%281%2B%5Cfrac%7B0.025%7D%7B4%7D%29%5E%28%5E4%5E%2A%5E3%5E%29%5C%5C%20%5C%5C%20A%3D%20400%281%2B0.00625%29%5E1%5E2%5C%5C%20%5C%5C%20A%3D400%281.00625%29%5E1%5E2%5C%5C%20%5C%5C%20A%3D%20431.053...)
So, the amount of total interest earned ![= (\$431.053...-\$400)=\$31.053... \approx \$30.00(Approximately)](https://tex.z-dn.net/?f=%3D%20%28%5C%24431.053...-%5C%24400%29%3D%5C%2431.053...%20%5Capprox%20%5C%2430.00%28Approximately%29)
25
If 15 is 60% of a number, it is 3/5 of the whole. Since 5 goes into 25 5 times, and 5 goes into 15 3 times, 15 is the 3/5 of 25.
I think the ones that would apply to this would be a. b. and c.
Since they are on the same line the slope doesn't change!
Hope I helped :)
Answer:
x = 14
Step-by-step explanation:
4x + 2x + 6 = 90
Combine like-terms
6x + 6 = 90
6x = 84
x = 14
