Question

kylie is feeding her chicken from a 30-pound bag. the chicken goes through 3\\(\frac{1}{2}\\) pounds of food each week. enter, in decimal form, how many pounds of food are left after 3 weeks. pounds

Explanation:

Step1: Convert mixed number to decimal

The weekly consumption is \( 3\frac{1}{2} \) pounds. Convert \( \frac{1}{2} \) to decimal: \( \frac{1}{2}=0.5 \), so \( 3\frac{1}{2}=3.5 \) pounds per week.

Step2: Calculate total consumption in 3 weeks

Multiply weekly consumption by 3: \( 3.5\times3 = 10.5 \) pounds.

Step3: Calculate remaining food

Subtract total consumption from initial amount: \( 30 - 10.5 = 19.5 \) pounds.

Answer:

19.5
