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.
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$
