Question 260326
We can translate this sentence
"Ten more than half the babies born at Mountainside Hospital last week were girls"
as follows
(i) G = (1/2)T + 10
where G = girls and T = total
(ii) B = 16.
(iii)T = G + B
--
substitute (ii) into (iii) and we get
 (iv) T = G + 16
substitute (Iv) into (i) and we get
G = (1/2)(G+16) + 10
or
G = (1/2)G + 8 + 10
which is
(1/2)G = 18
So, G  = 36.
girls = 36, boys = 16, total = 52
