In a cooking recipe, Roel needs 0.435kg of beef for lumpia, 0.640kg of beef for bola-bola, and Riza also needs a kilogram of beef for pinakbet to make it a total of 1.50kg of meat. How much kilogram of beef does Riza needs for pinakbet?

A. 0.425

B. 40.25

C. 42.50

D. 402.5

First, write the statement into a number sentence.

[tex]1.5 - (0.435 + 0.640) = n[/tex]

Solve.

[tex]1.5 - (0.435 + 0.640) = n \\ 1.5 - 1.075 = n \\ 0.425 = n[/tex]

Thus, Riza needs 0.425 kilograms of beef to cook pinakbet
