Annual rate = 1.05%
Simple interest formula is I = Prt * 100
Where P is principle, I is interest, r is rate and t is time.
Transpose to make r the subject
Prt * 100 = I
r = I/ Pt * 100
Substitute values into the equation.
Let I = $1260, P = $30,000 and t = 4 years
r = $1260/ $30,000 * 4 * 100
r = 0.0105 * 100
r = 1.05%
Answer: 15
Step-by-step explanation:
4/20 is your ratio. Simplify it and it'd be 1/5. This means in 1 mile has been walked in 5 minutes. 3 x 5 is 15, so it took Susan 15 minutes.
Answer:
x3
Step-by-step explanation:
Considering x4 and x3 actually power terms.
I mean: x4 is 
and x3 is 
.
Let's decompose the first term: 
Now it is clear that the common factor is .
Answer:
30 red cars
Step-by-step explanation:
3x + 5x = 240
8x = 240
x = 30
red:blue = 3:5
30
