Answer:

Terrell drove 200 miles one way

Step-by-step explanation:

Since his trip concluded at 9 hours, let's say that x = time traveled at 40 mph

and 9 - x = time traveled at 50 mph

D = (rate) x (time)

40x = 50(9 - x) -----Use Distributive property on the right side of the equation

40x = 450 - 50x -----Add 50x on both sides

90x = 450 ------Divide by 90 on both sides

We end up with x = 5 which is the value we need to determine the distance of our first trip, calculated by

D = 40x, or 40(5) = 200 mi

Hi!

Step-by-step explanation:

=$9,827,954 total sold

STEP 2:
Divide the total sold above by the 325 shrimpers.

=$30,239.858

Rounded to nearest dollar:
Each of the 325 shrimpers will take home $30,240.

Hope this helps! :)
