Answer: 13%
Step-by-step explanation:
We know that the formula to find the simple interest :
, where P is the principal amount , r is rate (in decimal )and t is the time period (in years).
Given : Albert borrowed $19,100 for 4 years. The simple interest is $9932.00. Find the rate.
i.e. P = $19,100 and t= 4 years and I = $9932.00
Now, Substitute all the values in the formula , we get
![9932=(19100)r(4)\\\\\Rightarrow\ r=\dfrac{9932}{19100\times4}\\\\\Rightarrow\ r=0.13\ \ \ \text{[On simplifying]}](https://tex.z-dn.net/?f=9932%3D%2819100%29r%284%29%5C%5C%5C%5C%5CRightarrow%5C%20r%3D%5Cdfrac%7B9932%7D%7B19100%5Ctimes4%7D%5C%5C%5C%5C%5CRightarrow%5C%20r%3D0.13%5C%20%5C%20%5C%20%5Ctext%7B%5BOn%20simplifying%5D%7D)
In percent, 
Hence, the rate of interest = 13%
Answer:
-10.76
Step-by-step explanation:
Let's solve your equation step-by-step.
4=314(1.5x)
Step 1: Flip the equation.
314(1.5x)=4
Step 2: Divide both sides by 314.
314(1.5x)/314
=
4/314
1.5x=2/157
Step 3: Solve Exponent.
1.5x=2/157
log(1.5x)=log(2/157)(Take log of both sides)
x*(log(1.5))=log(2/157)
x=
log(2/157)
log(1.5)
x=−10.760725
Answer:
x=−10.760725

Let x stand for a movie.
You can pay $4 every movie or $1.50 for every movie plus the original $10
4x = 1.50x +10
-1.50x -1.50x (Subtraction Property of Equality)
2.50x = 10
/2.50 /2.50 (Division Property of Equality)
x = 4
After 4 movies, the membership will cost less.
