Based on the tables showing the price of buying different amounts of two brands of sugar, Suman determined that Sweet Sugar was the better buy based on price alone. How much money per pound will Suman save if he buys the Sweet Sugar brand?
(1 point)
To determine how much money per pound Suman will save if he buys the Sweet Sugar brand, we need to compare the price per pound of the two brands.
For Sweet Sugar:
Price for 2.5 lbs = $0.75
Price per pound = $0.75 / 2.5 = $0.30/lb
For Super Sugar:
Price for 3.75 lbs = $1.16
Price per pound = $1.16 / 3.75 = $0.31/lb
Suman will save $0.01 per pound if he buys the Sweet Sugar brand compared to the Super Sugar brand.
To determine how much money per pound Suman will save if he buys the Sweet Sugar brand, we need to calculate the price per pound for both brands.
For Sweet Sugar:
Price per pound = Price / Weight
For each row in the Sweet Sugar table, we can calculate the price per pound as follows:
- For 2.5 lbs: Price per pound = 0.75 / 2.5 = 0.30 dollars per pound
- For 15.0 lbs: Price per pound = 4.50 / 15.0 = 0.30 dollars per pound
- For 30.0 lbs: Price per pound = 9.00 / 30.0 = 0.30 dollars per pound
- For 100.0 lbs: Price per pound = 30.00 / 100.0 = 0.30 dollars per pound
Therefore, the price per pound for Sweet Sugar is consistently 0.30 dollars per pound.
For Super Sugar:
Price per pound = Price / Weight
For each row in the Super Sugar table, we can calculate the price per pound as follows:
- For 3.75 lbs: Price per pound = 1.16 / 3.75 = 0.3093 dollars per pound
- For 10.0 lbs: Price per pound = 3.10 / 10.0 = 0.31 dollars per pound
- For 25.0 lbs: Price per pound = 7.75 / 25.0 = 0.31 dollars per pound
- For 110.0 lbs: Price per pound = 34.10 / 110.0 = 0.3109 dollars per pound
Therefore, the price per pound for Super Sugar ranges between 0.3093 and 0.3109 dollars per pound.
Since the price per pound for Sweet Sugar is consistently 0.30 dollars per pound, and the price per pound for Super Sugar ranges between 0.3093 and 0.3109 dollars per pound, Suman will save approximately 0.01-0.009 dollars per pound if he buys the Sweet Sugar brand.
To determine how much money per pound Suman will save if he buys the Sweet Sugar brand, we need to calculate the price difference per pound between the two brands of sugar.
First, let's calculate the price per pound for each brand. We can do this by dividing the price by the weight for each row in the table.
For Sweet Sugar:
Price per pound = Price / Weight
For example, for the first row:
Price per pound = 0.75 / 2.5 = 0.3
Similarly, we can calculate the price per pound for each row in the Super Sugar table.
Next, let's compare the price per pound for each brand. Subtract the price per pound of Sweet Sugar from the price per pound of Super Sugar for each row.
For example, for the first row:
Price difference per pound = Price per pound (Super Sugar) - Price per pound (Sweet Sugar)
Once you have calculated the price difference per pound for each row, calculate the average price difference per pound by summing up the price differences and dividing by the total number of rows.
Finally, Suman will save the average price difference per pound if he buys the Sweet Sugar brand.
