Skyler o na le dihutshe tse 100 mo seatleng sa gagwe tse di nang le mmala o mohibitswana, o botala jwa legodimo, le o bosweu. Sephatlo sa dihutshe ke tse dihibitswana, 3/5 ya dihutshe tse di setseng ke tsa botala jwa legodimo, mme tse di setseng ke tse bosweu. Skyler o na le dihutshe tse di kae tse bosweu?

Elly is organizing her books on the new bookcases her parents bought her. Each of the middle 2 shelves can hold 10 books. The bottom shelf can hold twice as many books as a middle shelf. The top shelf can hold 5 fewer books than the bottom shelf. If she has 110 books, how many bookcases does she need to hold all of them?
Fa sephatlo sa dihutshe e le tse dihibitswana, go na le 1/2*100= <<1/2*100=50>>50 dihutshe tse dihibitswana.
Palo ya dihutshe tse di setseng tse e seng tse dihibitswana ke 100-50 = <<100-50=50>>50
3/5 ya dihutshe tse di setseng ke tsa botala jwa legodimo, palogotlhe ya 3/5*50 = <<3/5*50=30>>30 dihutshe
Fa tse di setseng tsa dihutshe e le tse bosweu, go raya gore go na le 50-30 = <<50-30=20>>20 dihutshe tse bosweu.

The bottom shelf can hold 2 * 10 = <<2*10=20>>20 books.
The 2 middle shelves can hold a total of 2 * 10 = <<2*10=20>>20 books.
The top shelf can hold 20 – 5 = <<20-5=15>>15 books.
Each bookcase can hold a total of 20 books + 20 books + 15 books = <<20+20+15=55>>55 books.
To hold all of her books, she needs 110 / 55 = <<110/55=2>>2 bookcases.
