Explanation:
Anika is a smart shopper who loves to sew her own clothes. She has a big event coming up: her sister's wedding! She wants to make some beautiful dresses for herself and her family. She finds a nice cloth that costs ₹210 for 5 metres. How much will she pay for different lengths of cloth? Let's see:
We can use a simple equation to calculate the cost of the cloth. The equation is:
y = 42x
where y is the cost in rupees and x is the length in metres. Why 42? Because 210 divided by 5 is 42. Easy peasy!
Now let's plug in some values for x and see what we get.
If x = 2, then y = 42 x 2 = 84. So Anika will pay ₹84 for 2 metres of cloth.
If x = 4, then y = 42 x 4 = 168. So Anika will pay ₹168 for 4 metres of cloth.
If x = 10, then y = 42 x 10 = 420. So Anika will pay ₹420 for 10 metres of cloth.
If x = 13, then y = 42 x 13 = 546. So Anika will pay ₹546 for 13 metres of cloth.
| Length (metres) | Cost (rupees) |
| --------------- | ------------- |
| 2 | 84 |
| 4 | 168 |
| 10 | 420 |
| 13 | 546 |
Anika is happy with her calculations. She decides to buy 10 metres of cloth and make three dresses: one for herself, one for her sister, and one for her mother. She will have some cloth left over for accessories. She can't wait to show off her creations at the wedding!
