Answer:
$10.45
Step-by-step explanation:
You need to add up the total price before the sale and after then subtract
<em>18.95 + 7.99 = </em><em>$26.94</em>
<em>8.99 + 7.50 = </em><em>$16.49</em>
<em>26.94 - 16.49 = </em><em>$10.45</em>

Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
