A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwich

Zolol [24]

$\left \{ {{T+S=925} \atop {4T+6S=4524}} \right. \\ S=925-T \\ 4T+6(925-T)=4524 \\ 4T+5550-6T=4524 \\ -2T+5550=4524 \\ -2T=-1026 \\ T=513$
So they sold 513 turkey sandwiches

A wastewater treatment plant receives 20million gallons per day (mgd) of flow. This wastewater has a solid concentration of 384m

xxMikexx [17]

Answer:

64,092.73 pounds

Step-by-step explanation:

1 gallon = 3.78541 liter

1 pound = 453592 mg

In order to obtain the weight of solids that enter the plant each day, simply multiply the wastewater flow by the solids concentration and make the necessary unit adjustments:

$W=20,000,000\ gal*384\frac{mg}{L}*\frac{3.78541\ L}{1\ gal}*\frac{1\ lbs}{453592\ mg} \\W=64,092.73\ lbs$

64,092.73 pounds of solids enter the plant each day.
