Step 1
Step 2
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
The total in-store price for all items is R208.74. The total online price is R261.80.
The amount saved by shopping in-store would be calculated as:
Thus, Mrs Swartz would save R53.06.
Step 4
Determine the median price of the listed items for in-store shopping in the W&W store.
Answer
To find the median price for in-store shopping in the W&W store, the prices must be arranged in ascending order. The prices are as follows: R12.95, R14.99, R15.95, R19.95, R22.95, R23.99, R27.95.
The median is the average of the middle two values:
ext{Median} = rac{R19.95 + R22.95}{2} = rac{42.90}{2} = R21.45
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
The total number of items listed is 12. There are 2 items where the in-store price is equal to the online price.
The probability can be calculated as:
P = rac{ ext{Number of favorable outcomes}}{ ext{Total outcomes}} = rac{2}{12} = rac{1}{6}
