To create the table of values showing the amount of money remaining on the card after buying a certain number of cups of coffee, we can calculate the remaining amount for each quantity of coffee purchased. The original amount on the gift card is $15, and each cup of coffee costs $1.50.
Here’s the calculation for each number of cups of coffee:
-
For 0 cups:
- Remaining amount = $15 - ($1.50 * 0) = $15.00
-
For 1 cup:
- Remaining amount = $15 - ($1.50 * 1) = $15 - $1.50 = $13.50
-
For 2 cups:
- Remaining amount = $15 - ($1.50 * 2) = $15 - $3.00 = $12.00
-
For 3 cups:
- Remaining amount = $15 - ($1.50 * 3) = $15 - $4.50 = $10.50
Now we can summarize these values in a table:
| Number of Cups of Coffee (x) | Amount of Money Remaining on Card (A) | |-------------------------------|---------------------------------------| | 0 | $15.00 | | 1 | $13.50 | | 2 | $12.00 | | 3 | $10.50 |
To write an equation for A in terms of x, we can derive it from the relationship established in the calculations.
The amount of money remaining A can be calculated as: \[ A = 15 - 1.50x \]
Where:
- \( A \) is the amount of money remaining on the card,
- \( x \) is the number of cups of coffee purchased.
Thus, the equation representing the amount of money remaining on the card after buying \( x \) cups of coffee is: \[ A = 15 - 1.50x \]
