  • Let x be the price of Banana. and y for the Mangoes.

[tex] \blue x = \blue{40} \\ \red y = \red{ 80}[/tex]

  • Multiply the price to how many kilograms bought.

[tex]5 \blue{x} + 4 \red{y} = \purple n \\ 5( \blue{40}) + 4( \red{80}) = \purple n \\ \blue{200} + \red{320} = \purple n \\ \purple{520} = \purple n[/tex]

Thus, the total price of the given and bought fruits are ₱520.00
