Step 1
Step 2
Arrange, in ascending order, the prices for Store B.
Answer
The ascending order of prices for Store B is:
- Grey shorts: R39.99
- Grey school socks: R18.99 per pack
- White school socks: R11.99 per pack
- School shoes (girls): R159.99
- White shirt: R444.99
- School shoes (boys): R169.99
- Grey shirt: R54.99
Step 3
Step 4
Determine the missing value P, if Martha bought all the school items as advertised at Store A.
Answer
To calculate the total P:
- White shirt: R110.00
- Grey shirt: R163.00
- Grey shorts: R16.60
- Grey school socks: R40.50 for 2 packs
- White school socks: R85.00 for 2 packs
- School shoes (girls): R349.00
- School shoes (boys): R318.00
Total P = R110.00 + R163.00 + R16.60 + R40.50 + R85.00 + R349.00 + R318.00 = R1,081.10.
Step 5
The probability of selecting Store C to buy all the school items is 0.3333333333.
Answer
In this context, probability refers to the likelihood or chance of selecting Store C out of the three stores available to purchase all school items.
In decimal form, the probability is given as 0.3333333333.
