Which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river?
A. (-1.68)(1) + (-1.68)(0.5)
B. 1(-1) + 0.5(-0.68)
C. 1.5(-1) + 0.68
D. 1 + (0.5)(-1)(0.68)

Karin observed that the water level there fell 1.68 millimeters per year for 1.5 years. Which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river?

A. (-1.68)(1) + (-1.68)(0.5)

B. 1(-1) + 0.5(-0.68)

C. 1.5(-1) + 0.68

D. 1 + (0.5)(-1)(0.68)
