To determine how much money per pound Suman will save if he buys the Sweet Sugar brand, we need to calculate the difference in price per pound between the two brands.
For Sweet Sugar:
Weight (lbs.) Price ($)
2.5 0.75
15.0 4.50
30.0 9.00
100.0 30.00
To calculate the price per pound for the Sweet Sugar brand, we divide the price by the weight for each entry:
Price per pound = Price ($) / Weight (lbs.)
For each entry in the Sweet Sugar table:
For 2.5 lbs: Price per pound = 0.75 / 2.5 = 0.30
For 15 lbs: Price per pound = 4.50 / 15 = 0.30
For 30 lbs: Price per pound = 9.00 / 30 = 0.30
For 100 lbs: Price per pound = 30.00 / 100 = 0.30
The price per pound for the Sweet Sugar brand is consistently $0.30.
For the Super Sugar brand:
Weight (lbs.) Price ($)
3.75 1.16
10.0 3.10
25.0 7.75
110.0 34.10
To calculate the price per pound for the Super Sugar brand, we divide the price by the weight for each entry:
Price per pound = Price ($) / Weight (lbs.)
For each entry in the Super Sugar table:
For 3.75 lbs: Price per pound = 1.16 / 3.75 = 0.31
For 10 lbs: Price per pound = 3.10 / 10 = 0.31
For 25 lbs: Price per pound = 7.75 / 25 = 0.31
For 110 lbs: Price per pound = 34.10 / 110 = 0.31
The price per pound for the Super Sugar brand is consistently $0.31.
