8 0

Step-by-step explanation:

\frac{1}{3 } \times  \frac{30}{1}  = 10 \\  \\  \frac{10}{1}  \times  \frac{5}{6}  = 8.33 \\  \\  \frac{833}{100}  \times  \frac{6}{10}  = 4.998 \\  \\  \frac{4998}{1000}  \times  \frac{12}{1}  = 59.976

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?
Rama09 [41]

Answer:

The simple interest rate is 5%.

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?

We have that P = 4200, E = 630, t = 3. We have to find I.

E = P*I*t

630 = 4200*I*3

I = \frac{630}{4200*3}

I = 0.05

The simple interest rate is 5%.

Joshua’s goal is to have $5,000 after 4 years. Is this possible if he invests with a rate of  return of 6%?

We have to find T when P = 4200, t = 4, I = 0.06

So

E = P*I*t

E = 4200*0.06*4

E = 1008

T = E + P = 4200 + 1008 = 5208

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.
