Answer:
Problem: 5.24 - 4.93
Step-by-step explanation:
You subtract just like a normal Addition problem however you MUST make sure the decimal point line up,...
1st: subtract the 3 from the 4 [0.01]
2nd: subtract the 9 from the 2 (make the 2 a 12 (by carrying a one from the 5 (which then becomes a 4))) [0.30]
3rd: Finally subtract the 4 from the 4,... 0
<em>Answer = 0.31,...</em>
A more summed up answer: Subtracting (and adding for that matter) decimals happens exactly like normal. However you MUST MAKE SURE that your decimal points are lined up,... if you are subtracting a 0.09 from a 4.5 and the 4.5 doesn't have a hundredths place just remember that you can add a 0 on the end (4.50) without chancing it's value. (and then just subtract like normal)
Answer:
the amount invested at 1% = $4100
the amount invested at 9% = $2600
Step-by-step explanation:
Hello
let
A=amount invested at 1%
B=amount invested at 9%
the total amount invested is % 6700, so
A+B=6700 (1)
the profits generated by A= (c)
the profits generated by B=(d)
the total profit is $275,so
the amount invested at 1% = $4100
the amount invested at 9% = $2600
I hope it helps
