On a deposit of $100 at a simple interest rate of 20%, How many years would it take to double your money?

Mathematics

borishaifa [10]3 years ago

Answer:

5 years

Step-by-step explanation:

Formula to calculate simple interest

<h3>A = P(1 + rt)</h3>

Where:

<em>A = Future amount = 2(100)</em>

<em>P = Principal Amount = 100</em>

<em>r = Rate of Interest per year in decimal</em>

<em>r = R/100 = 20/100 = 0.2</em>

<em />

To find,

t = Time Period

Put value in the formula

200 = 100(1 + 0.2t)

200/100 = (1 + 0.2t)

2 =  (1 + 0.2t)

2 - 1 = 0.2t

1 = 0.2t

1/0.2 = t

t = 5 years

So, it will take 5 years to double money.

Let the total amount be x

Then Ali got 1/8x With 7/8x left

Juma got 7/40x with 7/10x left

Musa, Khalid and Mustafa got 7/30x each

since \frac{7}{30}x=600

7x=18000

x=\frac{18000}{7}=2571\frac{3}{7}

Tanzila is selling tickets to the MS127 musical. On the first day of ticket sales she sold 2 adults tickets and 10 child tickets
vekshin1

Answer:

One adult ticket is $4 and one child ticket is $7

Step-by-step explanation:

Make a system of equations

2x + 10y = 78

8x + 5y = 67

Solve by elimination, multiply the 2nd equation by -2

2x +10y = 78

-16x -10y = -134

Add the equations

-14x = -56

x = 4

The price of one adult ticket is $4

Plug 4 in as x to find y

2(4) + 10y = 78

8 + 10y = 78

10y = 70

y = 7

The price of one child ticket is $7
