Worked Solution & Example Answer:Gadibola bought Pringles (chips in a cylindrical container) on promotion at a shop - NSC Mathematical Literacy - Question 1 - 2021 - Paper 2

Step 1

Determine (in grams) the total mass of the Pringles promotion bought for R100.

Answer

To determine the total mass, we first find how many packs can be bought for R100. Each pack contains 6 Pringles weighing 110 g each. Thus,

Total number of Pringles: extTotalPringles=6imes6=36extPringles ext{Total Pringles} = 6 imes 6 = 36 ext{ Pringles}

Total mass in grams: extTotalMass=36imes110extg=3960extg ext{Total Mass} = 36 imes 110 ext{ g} = 3960 ext{ g}

Step 2

Write down the radius of a single Pringles container.

Answer

The diameter of the Pringles container is 64 mm. To find the radius, we use the formula:

ext{Radius} = rac{ ext{Diameter}}{2} = rac{64 ext{ mm}}{2} = 32 ext{ mm}

Step 3

Choose the letter of the answer that will make the following statement TRUE.

Answer

The correct letter is A, as the inner volume can be calculated in mm³.

Step 4

Determine the total number of days this promotion is available.

120 rated

Answer

The promotion is available from 11 Jan 2021 to 31 Mar 2021. We calculate the total days as follows:

Days in January: 21 (from 11 to 31) Days in February: 28 (2021 is not a leap year) Days in March: 31

Total days: extTotalDays=21+28+31=80extdays ext{Total Days} = 21 + 28 + 31 = 80 ext{ days}

Step 5

Calculate the price of two 110 g Pringles containers in this promotion.

Answer

The price for one container in the promotion is:

extPricefor6Pringles=R100 ext{Price for 6 Pringles} = R100 Price for one Pringle: ext{Price per Pringle} = rac{100}{6} = R16.67

To find the price for two containers: extPricefor2containers=2imesR100=R200 ext{Price for 2 containers} = 2 imes R100 = R200
