The future value of an investment is 10,110.28 if money was originally invested at 3.5% compounded semi annually for 5 years wha
timofeeve [1]

\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Compound Interest.

Since we know that formula for the Compound interest is :-

A= P(1+r/n) ^nt

here, A = total amount received at end, P= initial amount invested, r= rate of interest in decimal, t= time of years and n= frequency per year, so we get as,

=>10110.28 = P(1+0.035/2)^2*5

=>10110.28 = P (1+0.0175)^10

=>10110.28= P(1.0175)^10

=>so finally we get as

=>P= 1011.28/1.1894

=> P= 8500

5(1+8x)&lt;10x+25<br><br> Please give step by step
Ugo [173]

Answer:

x<2/3

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

40x+5<10x+25

Step 2: Subtract 10x from both sides.

40x+5−10x<10x+25−10x

30x+5<25

Step 3: Subtract 5 from both sides.

30x+5−5<25−5

30x<20

Step 4: Divide both sides by 30.

30x/30<20/30

x<2/3

Happy to help ya :)
