Answer:
The smaller number can be 8 or 
.
Step-by-step explanation:
Consider the provided information.
let the larger number is x and the smaller number is y
A positive number is 3 times another number.
If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.
Case I: If 2nd number is 2 times to the first number.
Substitute the value of x.
Now substitute the value of y in
Therefore, the smaller number is 8.
Case II: If 1st number is 2 times to the second number.
Substitute the value of x.
Therefore, the smaller number is .

<h3>Question 6</h3>
Normal cost of television = $500
Reduced cost = $350
<u>Cost reduction:</u>
<u>Percent reduction:</u>
Answer:
4.38%
Step-by-step explanation:
<em>Assuming simple interest</em>, we start by writing the formula for simple interest.
Where
SI is the interest amount (328.13)
P is the principal amount (2500)
r is the rate of interest (what we need to find)
t is the time, in years (t = 3)
Since we want rate of interest, we re-arrange the formula to get r in terms of the other variables. Shown below:
Now we simply plug-in the information we know and find r:
To convert into percentage, we multiply by 100:
r = 0.0438 * 100 = 4.38%
