Answer:
4)P = $615.38. 5)P = $1,482.35
Step-by-step explanation:
<u>4)P = $615.38</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
P = 640 / ( 1 + (0.04 × 1)) = 615.38461538462
P = $615.38
The principal investment required to get a total amount, principal plus interest, of $640.00 from simple interest at a rate of 4% per year for 1 years is $615.38.
<u>2)P = $1,482.35</u>
Equation:
P = A / (1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year.
Solving our equation:
P = 2016 / ( 1 + (0.12 × 3)) = 1482.3529411765
P = $1,482.35
The principal investment required to get a total amount, principal plus interest, of $2,016.00 from simple interest at a rate of 12% per year for 3 years is $1,482.35.
Hi Fareed134,
If you want to find the other lengths of the sides, all you have to do is take the side you know (10) and subtract it from 28. Then, divide it in half to get 2 longer sides, and divide 10 in half to get the 2 shorter sides.
28-10=18
18/2=9
10/2=5
the lengths of the other sides are 9,9,5 and 5.
Hope this helps! :)
Number of CDs Kitts sold last week = x = 84
Number of CDs she sold this week = y = 26
Hope this helps :DD !!
Answer: 532
Step-by-step explanation:
Let x be the number of students and y be the number of non-students.
Then, by considering the given information, we have
Multiply 2 on the both sides of equation (1), we get
Subtract (3) from (2), we get
Put the value of y in (1), we get
Hence, 532 student tickets were sold .
