ACTIVITY: To solve problems in context [LO 1.6.1]

When we buy something in a shop we receive a cash slip. We need to be able to understand and “read” the slip. If not, we will not be able to check if it really reflects what we have bought and paid for. Look at the following examples:

Table 1

1. Study the above examples and then answer the following questions:

1.1 When were the purchases made at

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.2 What does the biltong cost per kg? __________________________________

1.3 How many items were bought from Pick ’n Pay? _______________________

1.4 What % tax had to be paid at

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.5 How (with what) did the client pay at

Pick ’n Pay? ___________________________________________________

Ranch Meat Centre? _____________________________________________

1.6 Who was the cashier at Ranch Meat Centre? __________________________

1.7 What amount did the customer give her? _____________________________

1.8 At what time were the purchases made at

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.9 If your purchases are not according to the slip, how will you know which cashier helped you at Pick a Pay if you cannot remember what he/she looked like?

1.10 What does the * next to a few of the amounts on the Pick ’n Pay slip mean?

DO YOU STILL REMEMBER?

Explain to a friend how we round off to the nearest 10, 100 and 1 000.

** Can you explain how we would round off to the nearest 10 000?

2. When we go shopping, we can estimate to the nearest rand whether we will have enough money to pay.

Look at the following slip. Round off to the nearest rand and estimate how much you will have to pay for your shopping.

DO YOU STILL REMEMBER?

Your calculator has a memory that you can use to do calculations with more than

one operation correctly.

M+ : enables the calculator to save or memorise the answer

MR / RCM : these keys are pressed if you want to retrieve the memorised answers

e.g. (347 219 + 34 987) + (296 553 + 1 897 320)

Key in 347 219 + 34 987 = M+

Then key in 296 553 + 1 897 320 = M+

Then key in MR or RCM

Assessment
