The answer is $654.06.
5.5% of $575 is $31.63. 575 x 0.055 = 31.63
This means that in one year he earns $31.63. In two years it will be $63.25 (31.63 x 2 = 63.25)
Then in half a year it will be $15.81 (31.63/2 = 15.81)
Finally add 15.81 and 63.25 to get $79.06 which you then add to the initial $575 to get the total amount earned in 2 1/2 years which is $654.06.
The square root of 16 is 4
A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5
B: 15-4=11
+4. +4
————-
X= 15
C: 4(3) = 12
D: 50/5 = 10
Btw this should be easy, try doing it on to your own now.
183891 is the answer but you have to subtract it
