b) Calculate how much you can spend in seven days if you smake a box of twenty cigarettes a day each costing R20.00.

If you smoke a box of twenty cigarettes a day, each costing R20.00, you will spend R20.00 every day. Over seven days, your total expenditure would be R20.00 x 7 = R140.00. So, you can spend R140.00 in a week for your smoking habit. Now, think about some alternatives! Cutting back even a little can save a significant amount in a month. For instance, if you decide to smoke only 15 cigarettes a day instead, you'd only spend R105.00 over the week, leaving room for other enjoyable activities or saving for something special!
