Question

A cup and saucer together cost N$ 20.50 . A cup and two saucer cost N$ 27.00 . Find the cost of the cup and the saucer.

Answer 1

Answer: Cup-$14, Saucer-$6.5

Explanation:

Given

Cup and saucer costs $20.5

A cup and two saucer costs $27

Assume the price of cup and saucer are x and y

So, we can write

`\Rightarrow x+y=20.5\quad \ldots(i)\\\\\Rightarrow x+2y=27\quad \ldots(ii)`

Solving
`(i)\ \text{and}\ (ii)` we get

`x=\$\ 14, y=\$\ 6.5`

Thus, the cost of the cup is $14 and that of the saucer is $6.5
