Step 3
Calculate how much Mrs Swartz would be saving if she bought all the items listed in the table directly from the store rather than shopping online.
Answer
To calculate Mrs Swartz's savings, first, we find the total in-store price and the total online price.
Total In-store Price for P&P: R208.74 Total Online Price for P&P: R261.80
Total Savings = Total Online Price - Total In-store Price = R261.80 - R208.74 = R53.06.
Mrs Swartz would save R53.06 by purchasing all items directly from the P&P store.
Step 4
Determine the median price of the listed items for in-store shopping in the W&W store.
Answer
To find the median, we first arrange the in-store prices: 12.99, 14.99, 15.95, 15.95, 19.95, 22.95, 23.99.
The median is the average of the middle two numbers (15.95 and 19.95):
Median = (15.95 + 19.95) / 2 = 17.95.
Thus, the median price for in-store shopping at W&W store is R17.95.
Step 5
Calculate the probability of randomly selecting an item from the P&P store where the in-store price is exactly the same as the online price.
Answer
From the table, there are 12 items in total and 1 item (R14.89 for tea) where the in-store price matches the online price.
Probability = Number of matching prices / Total prices = 1 / 12 = 0.083 or 8.33%.
