Answer 1

money paid for potatoes = 1.5x

money paid for oninons = 2.25y

total mony paid = 1.5x + 2.25y

Answer 2

He pays birr (1.50x + 2.25y).

Step-by-step explanation:

Given that, the grocer buys x kg of potatoes at birr 1.50 per kg.

∴ the cost of x kg of potatoes is birr 1.50x

Also he buys y kg of onions at birr 2.25 per kg.

∴ the cost of y kg of onions is birr 2.25y

Thus total money paid by him is

= cost of x kg potatoes + cost of y kg onions

= birr (1.50x + 2.25y)

Note: Birr is the money unit in Ethiopia. It is 2.22 Indian rupee per unit birr.
