(103 + 219) + 78 = 103 + (n + 78).
Nilai n agar kalimat matematika tersebut bernilai benar adalah ....
Correct Answer
A. 219
Explanation
To make the equation (103 + 219) + 78 = 103 + (n + 78) true, the value of n should be 219. This is because when we add 103 and 219, and then add 78 to the sum, it should be equal to adding 103 and (n + 78). Therefore, n must be the same as the second number in the initial addition, which is 219.

The initial number of eggs at Wahyu's farm was 5,467. Bu Indah then bought 3,967 eggs. After that, the chickens at Wahyu's farm laid an additional 2,805 eggs. To find the current number of eggs at Wahyu's farm, we need to subtract the number of eggs bought by Bu Indah and add the number of eggs laid by the chickens. Therefore, the current number of eggs at Wahyu's farm is 5,467 - 3,967 + 2,805 = 4,305.

Rima membeli 5 buah donat dan 4 buah roti. Harga donat Rp2.500,00/buah dan harga roti Rp4.500,00/buah. Jika Rima membayar dengan dua lembar uang dua puluh ribuan, maka uang kembalian yang diterima Rima adalah ....
Correct Answer
C. Rp9.500,00
Explanation
Rima membeli 5 buah donat dengan harga Rp2.500,00/buah, sehingga total harga donat yang dibeli adalah 5 x Rp2.500,00 = Rp12.500,00. Rima juga membeli 4 buah roti dengan harga Rp4.500,00/buah, sehingga total harga roti yang dibeli adalah 4 x Rp4.500,00 = Rp18.000,00. Jadi, total harga keseluruhan adalah Rp12.500,00 + Rp18.000,00 = Rp30.500,00. Rima membayar dengan dua lembar uang dua puluh ribuan, yang totalnya adalah 2 x Rp20.000,00 = Rp40.000,00. Uang kembalian yang diterima Rima adalah Rp40.000,00 - Rp30.500,00 = Rp9.500,00.
