(x-1)+x+(x+1)=915
3x=915
x=305

Answer:ez just divise all
Step-by-step explanation:
2.5 rounds up to 3. Because the digit after the decimal point is 5 or more.
So u turn the percent into a decimal.
0.10
Now multiply 1200 * 0.10
1200*0.10= 120 ( 120 is the amount that is gonna increase)
So if it says 5 years, than your gonna multiply 120 * 5
120*5 =600
So your gonna add 600 to 1200.
So in five years your gonna be making 1,800.
An easier way would be to use prt
Principle * rate * time
1200 * 0.10* 5
= 600
So now you just add 600 to 1200
= 1800
