Answer:
Ronald originally had $166.
Step-by-step explanation:
Let's suppose that the amount of money that Ronald started with is x dollars.
We know that he starts of with x dollars, spends $128.15, and is left with $37.85. We can make an equation out of this:
x-128.15=37.85
Add 128.15 to both sides
x=166
Label the answer: $166.
We can check this by taking the answer (in this case it's $166) and subtracting $128.15. We should get $37.85, which was the amount of money he had left:
166-128.15=37.85 ✓
