Answer:
Equation: 15.25 + h = 18.60
Explanation:
Let's write down the important information from the question:
- Penelope had $15.25 saved in her coin jar after putting h dollars in the jar on Monday.
- Penelope has saved $18.60.
- She wants to know how much money she put in the coin jar on Monday.
We can use the following equation to determine how much money Penelope puts in the coin jar on Monday:
15.25 + h = 18.60
Subtracting 15.25 from both sides of the equation, we get:
15.25 + h - 15.25 = 18.60 - 15.25
h = 3.35
Therefore, Penelope put $3.35 in the coin jar on Monday.
