20% of $19,400 is $3,880
($19,400 / 5 = $3,880)
subtract 20% from the original value
($19,400 - $3,880 = $15,520)
it's now worth $15,520

Answer:
C and D
Step-by-step explanation:
So from the equation <em>y = 1.26x + 9.49</em> we can gather that <em>9.49</em> is an initial value because it has to be added to the number with a variable <em>( 1.26x)</em>
Because <em>1.26</em> has a variable of <em>x </em>and x represents a week, we know that the number<em> 1.26 </em>will increases in value depending on how many weeks have passed.
