Answer:
Option A for part A and $79 for part B
Step-by-step explanation:
W=2j, m=5w, (m+4)=6(j+4)
using w from first in second you get:
m=5(2j)=10j, m+4=6j+24
m=10j, m=6j+20, since m=m we can say
10j=6j+20
4j=20
j=5, and since m=10j
m=50
So the man is 50 years old
Lets Sean's age be x
Helen's age by y
x/y=3/5
x=3/5y
Second equation
2(x-2)=y-2
on solving u get Helen as 10 and Sean as 6
