Question

Mrs Lee plans to buy durians at the market. If she buys 12 kg of durian, she
would need another $17. If she buys 8 kg of durian, she would have $9 left.
How much money did Mrs Lee bring to the market?

Answer 1

Let the price of durian be x per kg

APQ:

12x-17=total amount

8x+9=total amount

APQ

$12x - 17 = 8x + 9$

$12x + - 8x = 9 + 17$

$4x = 26$

$x = \frac{26}{4} = 6.5$

so,

price of durian =$6.5 / kg

so, total money

=8x+9

=8*6.5+9

=$52+9

=$61

hope this helps you.
