Calculate the area of the floor:
Area = 1.6 x 2.3 = 3.68 square meters
Using the given formula: Pressure = force/area
200 = force / 3.68
Solve for force by multiplying both sides by 3.68
Force = 200 x 3.68
Force = 736 N/m^2
Correct to the nearest 5N/m^2 = 735 N/m^2
The answer is the very last option.

In mathematics, the statement if a, then b, says that if a is true, then be is true. If you think about it, this makes sense too. That means that the answer is C., because of the definition of the statement.
Answer:
Juan imprimió 7 páginas a color.
Step-by-step explanation:
Llamemos "b" a las copias en blanco y negro y "c" a las copias en color.
Juan imprimió 75 páginas. En forma simbólica es:
b + c = 75
b = 75 - c [1]
El costo de impresión de cada página en una biblioteca es de 5 centavos si es en blanco y negro o 50 centavos si es a color. En total pago $6.90. En forma simbólica es:
0.05b + 0.5c = 6.90 [2]
Si reemplazamos [1] en [2],
0.05(75-c) + 0.5c = 6.90
3.75 - 0.05c + 0.5c = 6.90
0.45c = 3.15
c = 7
