<span>6x+9y = 10500
x+y = 1480
Using elimination I get:
6x + 9y = 10500
-6x-6y = -8880
Add the 2 equations and I get 3y = 1620
Divide both sides by 3 and I get y = 540
Substitute that back in to 6x+9y = 10500.
I get that 6x+9*540 = 10500
9 * 540 = 4860
Subtract 4860 from both sides and I get 6x = 5640
Divide both sides by 6 and I get x = 940
So there must have be 940 children and 540 adults</span>
Answer:
$137.5
Step-by-step explanation:
45/100 X 250
= 11250/100 = 112.5
250-112.5 = 137.5
or
100%-45%=55%
55/100X250
=13750/100 = 137.5

If you mean just one, then only 7 babies in 28 years.
