Question

the coach of cricket team buys 3 bats and 6 balls for Rs 3900. later she buys another bat and 2 more balls of the same kind for Rs 1300. Represent this situation algebraically and geometrically.

Answer 1

let the cost of 1 bat and 1 ball be x and y respectively,
from the first situation. she bought 3 bats and 6 balls,
so it is,,
3x+6y= rs3900---------eq_1
 now from second situation,
x+2y= rs 1300----------eq_2

as we do in class 9 we make it's grph
by finding it's solutions of both equations.
