In the aquarium, the 5 adult sharks each eat 120 pounds of food every day. The 2 baby sharks each eat 70 pounds of food every day. This equation can be used to find t, the total pounds of food the sharks eat each day. t = (5 x 120) + (2 x 70) How many total pounds of food do the sharks eat each day?

• 42,140

• 460

• 670
