To provide a clear answer to your question, let's break it down step-by-step:
1. The customer asks for $1.50 in change, all in nickels.
2. To find out how many nickels to give, we need to determine the value of a nickel. A nickel is worth $0.05.
3. We can calculate the number of nickels by dividing the desired amount of change ($1.50) by the value of a nickel ($0.05).
4. Using the formula: Number of nickels = Amount of change / Value of a nickel, we can plug in the values: Number of nickels = $1.50 / $0.05.
5. When we perform the calculation, we get: Number of nickels = 30 nickels.
So, to give the customer $1.50 in change, all in nickels, you would need to give them 30 nickels.
