Here,
Time: 4 years
Rate: 5%
Simple interest:500$
So, principal:?
We know,
SI=P*T*R/100
500=P*4*5/100
500=20P/100
20P=50000
P=50000/20
P=2500$
So 2500$ is needed to make atleast 500$ interest in 4 years with 5% rate
Answer:
34 weeks
Step-by-step explanation:
Hello!
We can set up an equation to solve for the number of weeks.
Let w = the number of weeks he is saving up.
The equation is 
- 315 is the target amount
- 115 is the current amount
- 10w is the rate of growth
- 140 is the current debt
<h3>Solve for w</h3>
He needs to save up for 34 weeks.
Answer:
c≤8
Step-by-step explanation:
Let c be the number of copies that you can make
Each copy is 25 cents or .25
It must be less than or equal to 2 dollars
.25c ≤2.00
Divide each side by .25
.25c/.25 ≤ 2.00/.25
c≤8
Answer:
1.645 ft
Step-by-step explanation:
Divide the length of the board by the number of pieces it will be cut into
8.225/5=1.645 ft
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Diviode 140 by 2 to get X=70
