Answer:
The cost to make one tie is approximately £4.79
Explanation:
The details of the dimensions of the fabric needed to make the school tie are;
The length of the required fabric = 135 cm
The width of the fabric for the tie = 9 cm
The width of a roll of fabric when sold = 90 mm = 9 cm
The cost of the fabric per meter = £3.55
The width of the roll of fabric = The width of the fabric material required to make a tie
1 meter = 100 cm
The cost of 1 m (100 cm) of fabric = £3.55
Therefore;
The cost of the 135 cm of the fabric required for the tie, <em>c</em>, is found as follows;
c = £3.55 × 135/100 = £4.7925
The cost of the fabric required to make one tie giving the answer to two decimal place, c ≈ £4.79
