To determine how much Suman will save per pound by buying Sweet Sugar instead of Super Sugar, we first need to calculate the price per pound for each sugar brand.
**For Sweet Sugar:**
1. **2.5 lbs:** $0.75 / 2.5 lbs = $0.30 per lb
2. **15 lbs:** $4.50 / 15 lbs = $0.30 per lb
3. **30 lbs:** $9.00 / 30 lbs = $0.30 per lb
4. **100 lbs:** $30.00 / 100 lbs = $0.30 per lb
**Average price per pound for Sweet Sugar = $0.30**
**For Super Sugar:**
1. **3.75 lbs:** $1.16 / 3.75 lbs = $0.3093 per lb
2. **10 lbs:** $3.10 / 10 lbs = $0.31 per lb
3. **25 lbs:** $7.75 / 25 lbs = $0.31 per lb
4. **110 lbs:** $34.10 / 110 lbs = $0.3100 per lb
**Average price per pound for Super Sugar = $0.31**
**Calculating the savings:**
Savings per pound = Price per pound of Super Sugar - Price per pound of Sweet Sugar
Savings per pound = $0.31 - $0.30 = $0.01
Therefore, Suman will save **$0.01** per pound if he buys the Sweet Sugar brand.
