Nkgono sews dresses for children. The material costs R120, 50 per metre and she needs 3 metres of material to make a dress for a 6 -year old, 4,5 metres to make a dress for a 7 - year old and 5 metres to make a dress for 10-year old. The embroidery colton costs R15, 25 for a roll of 4 metres. She uses 3 rolls of cotton per dress. Use above information to answer the questions that follows \( \begin{array}{lll}3.1 & \text { How many metres of material will she need to make the above } 3 \text { dresses? } & \text { (2) } \\ 3.2 \text { What will the material cost for the three dresses? } & (2) \\ 3.3 & \text { Calculate in centimetre the length of the embroidery cotton that Nkgono is going to } \\ \text { use when sewing one dress. } & \text { (3) } \\ 3.4 & \text { Calculate the total amount that she will pay for the embroidery cotton? } & \text { (2) } \\ 3.5 & \text { What is the total cost of a dress for a } 10 \text { year old? } & \text { (3) }\end{array} \)

We are given the following: • Material costs R120.50 per metre. • For a 6‐year‑old dress – 3 metres are needed. • For a 7‑year‑old dress – 4.5 metres are needed. • For a 10‑year‑old dress – 5 metres are needed. • Embroidery cotton costs R15.25 per roll (each roll is 4 metres). • Nkgono uses 3 rolls of cotton per dress. Now, let’s answer each question step‐by‐step. ───────────────────────────── 3.1 How many metres of material will she need to make the above 3 dresses? Add the metres needed for each dress:   3 m + 4.5 m + 5 m = 12.5 m Answer: 12.5 metres. ───────────────────────────── 3.2 What will the material cost for the three dresses? Material cost = Total metres × Cost per metre   = 12.5 m × R120.50/m   = R1,506.25 Answer: R1,506.25. ───────────────────────────── 3.3 Calculate in centimetres the length of the embroidery cotton that Nkgono is going to use when sewing one dress. Each dress uses 3 rolls and each roll is 4 metres. Therefore, the length per dress:   3 rolls × 4 m/roll = 12 m Convert 12 metres to centimetres (1 m = 100 cm):   12 m × 100 = 1200 cm Answer: 1200 centimetres. ───────────────────────────── 3.4 Calculate the total amount that she will pay for the embroidery cotton? For one dress, the cost of cotton:   3 rolls × R15.25 per roll = R45.75 If the question refers to all three dresses, then:   3 dresses × R45.75 = R137.25 Answer: R137.25 for the three dresses. ───────────────────────────── 3.5 What is the total cost of a dress for a 10‑year‑old? For a 10‑year‑old dress:   Material required = 5 m   Material cost = 5 m × R120.50/m = R602.50 Embroidery cotton cost (per dress) = 3 rolls × R15.25 = R45.75 Total cost = Material cost + Embroidery cotton cost   = R602.50 + R45.75   = R648.25 Answer: R648.25. ───────────────────────────── Summary of Answers: 3.1 12.5 metres 3.2 R1,506.25 3.3 1200 centimetres 3.4 R137.25 (for three dresses) 3.5 R648.25
