Wastewater is filling barrels at the rate of 7 quarts per hour. the recycling facility picks up 25 full barrels on each trip, and each barrel holds 48 quarts of wastewater. how many days are between each pickup? show your work to receive full credit. (10 points)

if wastewater is filling barrels at the rate of 7 quarts per hour and there are 24 hours in a day we start with,

7 x 24 = 168

and if the recycling facility picks up 25 full barrels on each trip, and each barrel holds 48 quarts of wastewater,

25 x 48 = 1,200

so we know that they fill 168 quarts each day and the facility makes a trip each time they've filled 1,200

1,200 ÷ 168 = 7.14285714286

so, there are 7 days between each pickup ( they come once a week )
