Question

John went to the supermarket with 230 dollars in his wallet. He bought 2.5 kg of apples, 3 kg of carrot and 1.5 kg of meat. How much money did he have in his wallet after the shopping?

wallet - бумажник (кошелек)

Food Prices:

1 kg of apples - 15 dollars

1 kg of carrot - 7 dollars

1 kg of meat - 27 dollars

Answer: John has ------ dollars in his wallet after the shopping.

Answer 1

If 1 kg of apples —> 15$ so 2.5 kg —> 37,5 (2,5*15=37,5)
if 1kg of carrots —> 7$ so 3kg —>21$ (7*3=21)
if 1 kg of meat —> 27$ so 1.5 kg —>40,5$ (27*1.5=40,5)
затем просто складываем суммы всех покупок 37.5+21+40,5=99$ (потрачено)
теперь от 230-99=131$ (осталось в кошельке )
ответ: 131$
