Four oranges sell for Nx and three mangoes sell for Ny. Olu bought 24 oranges and 12 mangoes. How much did he pay in terms of x and y?
- N94x + 6y)
-
N(6x + 4y)
- N(24x + 12y)
- N(12x + 24y)
The correct answer is: B
Explanation
4 oranges sell for Nx, 1 orange will sell for \(\frac{Nx}{4}\)24 oranges will sell for: \(\frac{Nx}{4} \times 24\) = n6x
3 mangoes sell for Ny, 1 mango will sell for \(\frac{Ny}{3}\)
12 mangoes will sell for \(\frac{Ny}{3} \times 12\) = 4Ny
total money pay N6x + N4y = N(6x + 4y)
