Question

Jeannie is 8 years older than her younger sister April. When added together, their ages equal 198. How old is April?

Answer 1

jeannie - 8 years =age of april
so
j - 8 = a
jeannies age + Aprils age = 198
so
j+a=198
so we have two equations
1) j+a=198
and
2) j-8=a
so plug the 2nd into the first for a
j+a=j+j-8=198
2j=206
j=103
so
a=j-8 = 103-8 = 95
april is 95

Answer 2

any time you have a problem like this with ages, subtract the difference and divide by 2 to get the lower of the 2 ages

198 - 8 = 190

190/2 = 95

Answer 3

95
