a 50 pound bag of glossy coat horse feed cost $23.50. A 25 pound bag cost $15.50. How much money per pound would you save by buying the bag with the lower unit price?
you have to solve for amount per pound of each:
23.5/50 = ?
15.5/25 = ?
then subtract the answers you got to get the amount per pound that can be saved by buying the lower unit price.
hope this helps. :)
4oes 23.5/50 = 0.47;
right. :)
how about 15.5/25 = ?
0.62?
right. :)
now, subtract them to get amount per pound that can be saved.
0.14 punds?
0.15*
right. :)
but since it's amount per pound, the units must be in dollars/pound.
To find out how much money per pound you would save by buying the bag with the lower unit price, you need to calculate the difference in unit prices between the two bags.
First, let's determine the unit price for each bag:
For the 50-pound bag:
Unit price = Cost / Weight
Unit price = $23.50 / 50 pounds = $0.47/pound
For the 25-pound bag:
Unit price = Cost / Weight
Unit price = $15.50 / 25 pounds = $0.62/pound
Now, let's calculate the difference in unit prices:
Difference in unit prices = Higher unit price - Lower unit price
Difference in unit prices = $0.62/pound - $0.47/pound
To calculate the savings, it is important to note that the lower the unit price, the better deal it is. So, in this case, the lower unit price is $0.47/pound.
Now, let's calculate the savings in dollars per pound:
Savings per pound = Difference in unit prices
Savings per pound = $0.62/pound - $0.47/pound
Savings per pound = $0.15/pound
Therefore, by buying the bag with the lower unit price, you would save $0.15 per pound compared to the higher-priced bag.
