If one shop is selling ice cream for $15 for 3 pounds and the other shop is selling 4 pounds
for $18...what is the COST of the cheaper ice cream per pound?
To find the cost of the cheaper ice cream per pound, we need to compare the price per pound of ice cream in both shops.
In the first shop, the price for 3 pounds of ice cream is $15.
Therefore, the price per pound of ice cream in the first shop is $15/3 pounds = $5/pound.
In the second shop, the price for 4 pounds of ice cream is $18.
Therefore, the price per pound of ice cream in the second shop is $18/4 pounds = $4.50/pound.
Comparing the prices, we can see that the second shop is selling ice cream at a cheaper rate, with the cost of $4.50 per pound.
