Answer:
Principal = 3500
Time = 8 years
We are given that compound quarterly
So, No. of compounds per year = 2
Rate of interest = 5%
Formula : 
Substitute the values :


Interest = 3863.345 - 3500 = 363.345
Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345
5x + 4y = 24
Substitute y for 1
5x + 4 = 24
5x =20
x = 4
Answer:
x=3
Step-by-step explanation:
....................
10 - 2.99 = 7.01 and 7.01 - 1.07 = 5.94 so you will get 5.94 in change
y + 2007 = 5/29x
5/29 is the slope and 2007 is the y-intercept
