Perhatikan cerita berikut!
Milky membeli 1 kilogram mangga dan 3 kg apel dijual dengan harga Rp105.000,00. Sedangkan Nurma membeli 2 kg mangga dan 1 kg apel adalah Rp 60.000,00. Buatlah model matematika dari permasalahan diatas!
3
Open Ended
Langkah 1 adalah memisalkan dengan symbol/variable
Misal :
Banyaknya Mangga (dalam kilo) = ...
Banyaknya Apel (dalam kilo) = ...
4
Nama | Buah yang dibeli | Bentuk aljabar | Harga | Model matematika |
|---|---|---|---|---|
Milky | | m+3a | 105.000 | m+3a=105.000 |
Nurma | | 2m+a | 60.000 | 2m+a=60.000 |
5
Match
Maka model matematika dari soal diatas adalah
Dengan menjodohkan berikut ini
𝑚 + 3𝑎
2𝑚 + 𝑎
2𝑚 + 2𝑎
2𝑚 - 𝑎
𝑚 + 4𝑎
105.000
60.000
110.000
100.500
115.000
105.000
60.000
110.000
100.500
115.000
