Cindy bought 3 pounds of candy for $2.16. At this rate , how much would the candy have cost if she had brought only 2 pounds?
To find out how much the candy would have cost if Cindy had bought only 2 pounds, we can set up a proportion using the given information:
3 pounds of candy costs $2.16
Let x be the cost of 2 pounds of candy.
We can set up the following proportion:
3 pounds / 2 pounds = $2.16 / x
Using cross multiplication, we have:
3 * x = 2 * $2.16
3x = $4.32
Dividing both sides of the equation by 3:
x = $4.32 / 3
x = $1.44
Therefore, if Cindy had bought only 2 pounds of candy, it would have cost $1.44.
To find out how much the candy would have cost if Cindy had bought only 2 pounds, we need to determine the cost per pound at the current rate.
Given that Cindy bought 3 pounds of candy for $2.16, we can calculate the cost per pound by dividing the total cost by the number of pounds:
Cost per pound = Total cost / Number of pounds
So, the cost per pound is:
Cost per pound = $2.16 / 3 pounds
Cost per pound = $0.72
Now, we can determine how much the candy would have cost if she had bought only 2 pounds. To do that, we multiply the cost per pound by the number of pounds:
Cost of 2 pounds of candy = Cost per pound * Number of pounds
Cost of 2 pounds of candy = $0.72 * 2 pounds
Cost of 2 pounds of candy = $1.44
Therefore, if she had bought only 2 pounds of candy instead of 3 pounds, it would have cost her $1.44.
2.16 / 3 = $0.72 per pound
How much does 2 pounds cost?
