Answer:
$5.61
Step-by-step explanation:
Since David only has $9.39 but he needs $15.00 for his purchase. So, you would subtract the $9.39 from the $15.00 to see how much more money David needs to make this purchase.
15.00 - 9.39
When you carry out this problem, it equals $5.61.
Therefore, David needs $5.61 to be able to complete his purchase

Answer:
(4.2x100).(5.7x100) = 239.400
Step-by-step explanation:
We need to determine the product of (4.2x100).(5.7x100).
We know that when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For that reason, we can multiply all together, and the result will be the same regardless of the order of the multiplicands:
Then:
(4.2x100).(5.7x100) = 4.2x100x5.7x100 = 420x570= 239.400
