David has $9.39 but needs $15.00 to make a purchase. How much more does he need?
elena-14-01-66 [18.8K]

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
