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:
144
Step-by-step explanation:
Step 1: Find the sum of interior angles
Formula: 180(n - 2)
180(10 - 2)
180(8)
1440
Step 2: Assuming the 10-sided polygon's angles are all congruent, divide 1440 by 10
1440/10
144 degrees to each angle for all 10 angles.
