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.
