Answer:
3527
Step-by-step explanation:
Using our compound interest formula we can plug in all of our given values and solve for P.
A(t)=P(1+r/n)^nt
5,000=P(1+0.07/12)^12(5)
P=5000/(1+0.07/12)^60
P≈$3,527
No they arent proportional

Answer:
1,120 cm³
Step-by-step explanation:
Hello!
<u>Think about it this way:</u> There is a rectangular prism, with lengths of 20cm, 12cm, and 10cm, and another rectangular prism cut out of it with lengths, of 8cm, 8cm, and 20cm.
<h3>Larger rectangular prism</h3>
Volume = L * W * H
- V = 20cm * 12cm * 10cm
- V = 2,400cm³
<h3>Cut-Out Rectangular Prism</h3>
V = L * W * H
Subtract:
The total volume is 1,120cm³
Divide 430 by 75 to get 1% of the price.
430 / 75 = 5.733333...
Multiply that answer by 100 to get the original price.
5.73333... x 100 = 573.3333...
That will be your answer.
To double check your work, you can multiply 573.333... by 75 to see if the number in the problem (which was 75% of the original price) matches.
573.3333... x 75 = 430.
Hope that helped! :)
