Final answer:
To find the weight of 70 empty soda cans, we calculate the weight of one can (0.07 pounds) and multiply by 70, resulting in 4.9 pounds.
Step-by-step explanation:
If 50 empty soda cans weigh 3.5 pounds, finding the weight of 70 empty soda cans involves a simple proportion. First, we calculate the weight of one can by dividing 3.5 pounds by 50, which gives us the weight of a single can. Then, we multiply that weight by 70 to find the weight of 70 cans.
Let's do the math:
- Weight of one can = 3.5 pounds / 50 cans = 0.07 pounds per can.
- Weight of 70 cans = 0.07 pounds per can × 70 cans = 4.9 pounds.
Therefore, 70 empty soda cans would weigh 4.9 pounds.
