Theo has $51. Capri has $17. Leo has $7. $51+$17+$7=$75.
The amount of money that Davis has in this scenario is; $50
<h3>How to solve algebra word problems?</h3>
Let the amount of money he has be $X.
Now, if he buys 10 notebooks, he will have $10 left. Thus;
X - 10n = 10 -----(1)
If he buys 15 notebooks, he will be $10 short. Thus;
X - 15n = -10 ------(2)
Subtract eq 1 from eq 2 to get;
-5n = -20
n = -20/-5
n = 4
Thus;
X - 10(4) = 10
X = 10 + 40
n = $50

<u>The postal service delivered:</u>
7.14 × 1010 pieces of mail in December
