Question 10

antoniya [11.8K]

Answer:

$11,500 was invested at 13%.

$17,500 was invested at 4%

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:

$T = E + P$

In this question:

Loans totaling 29,000.

P was invested at 13%

29000 - P was invested at 4%.

First investment:

Principal P.

Interest 13% = 0.13.

One year, so t = 1.

$E_{1} = P*0.13*1$

$E_{1} = 0.13P$

Second investment:

Principal 29000 - P.

Interest 4% = 0.04.

One year, so t = 1.

$E_{2} = (29000-P)*0.04$

The total interest earned for both loans was $2,195.00.

This means that $E_{1} + E_{2} = 2195$

$E_{2} = 2195 - E_{1}$

So we solve the following system:

$E_{1} = 0.13P$

$E_{2} = (29000-P)*0.04$

$2195 - E_{1} = (29000-P)*0.04$

$2195 - 0.13P = 1160 - 0.04P$

$0.09P = 2195 - 1160$

$P = \frac{2195 - 1160}{0.09}$

$P = 11500$

$11,500 was invested at 13%.

29000 - 11500 = 17500

$17,500 was invested at 4%

RSM QUESTION NEED HELP!!!!!! A biker traveling at his usual speed can go from his house to work in 4 hours. When the weather is

kogti [31]

<h3>Answer: 216 miles</h3>

=======================================

Work Shown:

d = distance from work to his house

x = speed when weather is good

y = speed when weather is bad

y = x-6 since he travels 6 mph slower

------------------------

On a good weather day, he travels for 4 hours and goes at x mph

distance = rate*time

d = r*t

d = x*4

d = 4x

----------------------

On a bad weather day, he travels 4.5 hours (half hour more than 4 hrs) and goes at y = x-6 mph

d = r*t

d = y*4.5

d = 4.5y

d = 4.5(x-6) .... replace y with x-6

d = 4.5x-27 .... distribute

----------------------

The values of d for both equations are the same, as the biker is traveling the same distance. So we can equate the two right hand sides (RHS) and solve for x.

4.5x-27 = 4x

4.5x-4x = 27

0.5x = 27

x = 27/0.5

x = 54

The biker's speed on a good weather day is 54 mph.

A bad weather day's speed would be y = x-6 = 54 - 6 = 48 mph.

----------------------

Now compute the value of d

d = 4x

d = 4*54

d = 216

The biker travels 216 miles on a good weather day

or,

d = 4.5*y

d = 4.5*48

d = 216

the biker travels that same distance on a bad weather day.
