Answer:
The rate of simple interest is 25.89 %
Step-by-step explanation:
Given as :
The principal = $2350
The Amount = $2500
The time period = 90 days = 
year = 0.2465 year
Let The rate of interest = R %
So, Interest = Amount - Principal
Or, Interest = $2500 - $2350 = $150
<u>From Simple Interest method </u>
Simple Interest = 
Or, $150 = 
or, $150 × 100 = $579.275 × Rate
So, Rate = 
∴ Rate = 25.89 %
Hence The rate of simple interest is 25.89 % Answer
To solve this, you need to isolate/get the variable "c" by itself in the equation:
4c + 8c = -55 + 3c You can first combine like terms (4c and 8c)
12c = -55 + 3c Subtract 3c on both sides
9c = -55 Divide 9 on both sides
Answer:
$20.
Step-by-step explanation:
If she owes 4 people 5 dollars each, you multiply 5 and 4 to get the full amount of money altogether. In this case, the equation is
5*4=20
$195 x 40%
195 x .40 = 78
The price decrease is $78.00
Hope this helps. :)
