HARRIET BOUGHT CHRISTMAS CARDS.
SHE BOUGHT 1 BOX WITH 15 CARDS FOR $18.00,
1 BOX WITH 12 CARDS FOR 20.00, AND 2 BOXES WITH 10 CARDS FOR $8.00 EACH.
WHAT WAS THE AVERAGE PRICE SHE PAID PER CARD?
18 + 20 + 16 = $54
15 + 12 + 10 + 10 = 47
54 / 47 = ?
To find the average price Harriet paid per card, we need to determine the total amount she spent on cards and divide it by the total number of cards she bought.
First, let's calculate how much Harriet spent on each type of box:
- The box with 15 cards cost $18.00, so the price per card is $18.00 divided by 15 cards, which is $1.20 per card.
- The box with 12 cards cost $20.00, so the price per card is $20.00 divided by 12 cards, which is $1.67 per card.
- The two boxes with 10 cards each cost $8.00 each, so for both boxes, she spent $8.00 + $8.00 = $16.00. The total number of cards in these two boxes is 2 boxes * 10 cards per box = 20 cards. Therefore, the price per card is $16.00 divided by 20 cards, which is $0.80 per card.
Now, we need to calculate the total amount of money Harriet spent and the total number of cards she bought:
- For the box with 15 cards, Harriet spent $18.00 and bought 15 cards.
- For the box with 12 cards, she spent $20.00 and bought 12 cards.
- For the two boxes with 10 cards each, she spent $16.00 and bought 20 cards.
Adding all these together, Harriet spent $18.00 + $20.00 + $16.00 = $54.00 in total and bought 15 cards + 12 cards + 20 cards = 47 cards.
To find the average price per card, we divide the total amount Harriet spent by the total number of cards she bought:
Average price per card = Total amount spent / Total number of cards
Average price per card = $54.00 / 47 cards ≈ $1.15 per card
Therefore, the average price Harriet paid per Christmas card was approximately $1.15.
