Question

a study suggests that 75% of household solid waste can be recycled. however, the average person only recycles 30% of his or her solid waste. if the average person produces 4.5 pounds of solid waste a day, approximately how many more pounds of solid waste could be recycled compared to the amount they currently recycle?
choose 1 answer:
a 1.35 pounds
b 2.03 pounds
c 3.38 pounds
d 11.25 pounds

Explanation:

Step1: Calculate amount that can be recycled

The amount of solid - waste that can be recycled is 75% of 4.5 pounds. So, $0.75\times4.5 = 3.375$ pounds.

Step2: Calculate amount currently recycled

The amount of solid - waste currently recycled is 30% of 4.5 pounds. So, $0.3\times4.5=1.35$ pounds.

Step3: Calculate the difference

Subtract the amount currently recycled from the amount that can be recycled. $3.375 - 1.35 = 2.025\approx2.03$ pounds.

Answer:

B. 2.03 pounds
