To find the cost in dollars of 3 pounds of almonds, we can set up a proportion based on the given information:
4 pounds of almonds cost $10.
Let x represent the cost in dollars for 3 pounds of almonds.
We can set up the proportion as follows:
(4 pounds) / ($10) = (3 pounds) / (x dollars)
Now, we can solve for x:
4 / 10 = 3 / x
Cross-multiply:
4x = 30
Now, divide both sides by 4 to isolate x:
x = 30 / 4
x = 7.5
So, 3 pounds of almonds will cost $7.50.
