Gabriel will be 20, Elias will be 10

We can use an equation to map out and solve for each age.

Years gone by = x

12+x=2(2+x)

12+x=4+2x

x=8

12+8=20, 2+8 =10

First we need to find the number of jobs lost from 2008 to 2018. This is a 10 year period, so at an average loss of 1.7 thousand jobs per year the total loss of jobs over the 10 years will be:
$1.7\times10=17\ thousand\ jobs.$
Therefore the percent change will be:
$\frac{-17}{63.1}\times100=-27\ percent \ rounded\ to\ the\ nearest\ percent.$
