Answer:
18.8
Step-by-step explanation:
To find our x-value, we need to subtract 1998 from 2006
2006-1998=x=8
Now we plug it into the equation given
S=1.7x+5.2 (as you can see I manipulated it so that we can solve for S)
S=1.7(8)+5.2
S=13.6+5.2
S=18.8
Answer:
18.8 billion dollars
Step-by-step explanation:
S - 1.7x = 5.2
x = 2006 - 1998 = 8
S - 1.7(8) = 5.2
S - 13.6 = 5.2
S = 5.2 + 13.6
S = 18.8
