Answer:
he invested $10,000 at 7% and $12,000 at 6%
Step-by-step explanation:
- There are 2 equations that appear from this problem
- X+Y=22,000 and 0.07x + 0.06y = 1420
- Lets start by simplifying X+Y=22000
Y = 22000 - x
- now plug this into the Y value for the other equation
0.07x + 0.06(22000-x) = 1420
0.07x + 1320 -0.06x = 1420
0.01x = 100
X = 10000
- now plug 10000 into x for the simplified equation
Y = 22000 - 10000
Y = 12000
3% = 3/100 = 0,03
When it's compount interest it's 1,03 because you gain 3% more from what you already have.
All you need to do
1,03•2000=2060$ for the first year
And then for the second year, you take the actual amount after one year of 3%
1,03•2060=2121,8
After two years, there will be 2121,8$

I assume take the z score or it would be about 30% because of the 60, 95, 97.5 rule which has a technical name that I can't remember
Answer:
36
Step-by-step explanation:
3/4y=6-1/3c
3/4y+1/3c=6
multiplied 6 into equation to get 2c
9/2y+2c=36
so 2c+9/2y=36
