The first one is the answer because he starts with $300 (which would be the b in this case) and he gets $5 for EACH customer (so that would be 5x)
7,000,000,000 + 0 + 50,000,000 + 1,000,000 + 0 + 0 + 4,000 + 200 + 60 + 4

Step 1. Simplify 9^2 to 81
81 <span>÷ (-3)^0
Step 2. Use Rule of Zero: x^0 = 1
81 </span><span>÷ 1
Step 3. Simplify
81</span>
The answer is 12
12-(5+3)=4
4+8=12
