Hi there
To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question
While the amount invested at 5% is
6000-4000=2000
Good luck!
The answer is C
Radius is 8.2 and circumference is 51.52
X(.07 )+x = 14.70
x = 13.73831775
43.94 / 5.2 = 845 is impossible because it would mean that 845 * 5.2 is equal to 43.94 which would be a non sense.
Even if you multiply 84.5 * 5.2 you will still get a bigger result than 43.94 obviously.
The only way this division would make sense, it is if the result is 8.45 so the decimal point should be before the 4 and not after it so June is not correct.
GOod luck :)
21 divided by 7 is 3. So he would have ate 3 scopes a day.
