Answer 2

Answer:

I need to pay 36 pesos.

Step-by-step explanation:

Given, I brought instant noodles for 7.75 pesos and sardines for 16.00 pesos and 2 sachets of coffee for 12.25 pesos.

So,cost of noodles $= 7.75 \: pesos$

Cost of sardines $16 \: pesos$

and cost of 2 sachets of coffee $= 12.25 \: pesos$

So,total cost of all items

$= 7.75 + 16 + 12.25 \\ = 36 \: pesos$

This is a problem of Mathematics.

Some important Mathematics formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
