It depends on the quality of the balls. It also depends on where you are buying them. Do you have any more details?
Answer:
x = -(h+g) / f
Step-by-step explanation:
-fx - g = h
-fx = h + g
x = (h + g) / -f
x = -(h+g)/f
This means that 3/10 are red and that 7/10 are red, so 7/10(80) = 56blue marbles and 3/10(80)= 24red marbles
Given:
Principal (P)= $1,000
Rate of interest (R)= 4% = 0.04
Simple interest (I)= $100
To find:
The time for which she deposits $1000 into a savings account at 4% simple interest.
Solution:
The formula for simple interest is
On substituting P=1000, R=0.04 and I=100 in the above formula, we get
Divide both sides by 40.
Therefore, the required time is 2.5 years.
