Dear Robert, My son and I are thrilled at your kind offer to have us as visitors any time in the summer. Do you think we could possibly visit you on a sporting trip to Britain in the later part of June? What I mean by «sporting trip» is that we should not like to cause too much inconvenience and should be grateful for any camp-bed arrangement. My husband wishes me to give you his regards and to thank you for extending your invitation to him as well. It is very kind of you indeed. He is very sorry he does not feel up to any trip yet. He will write to you himself. Many thanks and best regards to you all from all of us here. Yours ,
Решение: Обозначим количество закупленных арбузов базой по цене 5 руб за (х) кг, тогда было закуплено арбузов по цене 10 руб (х-150) кг Общая сумма закупки в рублях составила: 5*х+10*(х-150)=5х+10х-1500=15х-1500 (руб) Было продано арбузов на сумму, или выручка от реализации (х+х-150)*7,5=(2х-150)*7,5=15х-1125 (руб) Прибыль от продаж составляет: (15х-1125)-(15х-1500)=15х-1125-15х+1500=375 (руб) Рентабельность равна: прибыль/выручка от реализации *100% По условию задачи рентабельность базы равна 25% Отсюда: 375/(15х-1125)*100%=25% 375/(15х-1125)=0,25 375=0,25*(15х-1125) 375=3,75х-281,25 3,75х=375+281,25 3,75х=656,25 х=656,25 : 3,75 х=175 (кг яблок закупленных по цене 5 руб за 1 кг) 175-150=25 (кг яблок закупленных по цене 10 руб за 1кг)
ответ: Закуплено яблок по цене 5руб за 1кг -175руб, по цене 10 руб за 1 кг - 25 кг
