Answer:
9 and 16
Step-by-step explanation:
let the two numbers are X and Y
X+Y=24
X^2-Y^2=144
solve simultaneously
Let the number of Blue casset be b and that of green be g.
Thus the total number of cassets will be:
b+g=16
hence
g=16-b.......i
The total amount was:
45b+55g=830..ii
plugging i in ii we get:
45b+55(16-b)=830
45b+880-55b=830
simplifying
45b-55b=830-880
-10b=-50
thus
b=5
hence
g=16-5=11
number of blue cassets was 5 and that of green was 11
Answer:
$80
Step-by-step explanation:
First you take 500 and multiply by 16% or .16.
You should get 80.
A tip for the future is when you have a percentage just move the decimal place to the left twice.
ie. 50%=.50, 125%=1.25, 2%=.02
I hope this helps :)
