To find out how many gift points Maryanne needs to get a $75 gift card, we can analyze the given information:
- Maryanne redeemed 4000 gift points for a $20 gift card.
- Maryanne redeemed 10,000 gift points for a $50 gift card.
To determine the value of each gift point, we can calculate the "exchange rate" by dividing the value of the gift card by the number of gift points redeemed:
- For the $20 gift card: 4000 gift points / $20 = 200 gift points per dollar.
- For the $50 gift card: 10,000 gift points / $50 = 200 gift points per dollar.
Since the exchange rate is the same for both gift cards, we can conclude that Maryanne needs 200 gift points for each dollar on the gift card.
To find out how many gift points she needs for a $75 gift card, we can multiply the number of dollars by the exchange rate:
- $75 * 200 gift points per dollar = 15,000 gift points.
Therefore, Maryanne needs 15,000 gift points to get a $75 gift card.
