To find the rate of increase or decrease, we need to calculate the percent change between last year's enrollment and this year's enrollment.

Percent change = (new value - old value) / old value x 100%

Percent change = (390 - 435) / 435 x 100%

Percent change = -45 / 435 x 100%

Percent change = -10.3448...%

Rounded to the nearest tenth of a percent, the rate of decrease is -10.3%, so the best choice is C, -10.3.
