Step-by-step explanation:
Number of pounds of banana needed = 5 pounds
Cost per pound of banana = 0.50
To solve using place value blocks :
Ignoring the decimal in the cost per pound:
We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.
5 * 5 = $25
Now we can add the one decimal point (in the cost per pound) to our result
Then we have $2.5
Hence, total cost = $2.5
