Final answer:

For every one dollar increase in price, the number of donuts sold decreases by 12.

Step-by-step explanation:

The regression equation given is y = 100 - 12.00x, where y represents the number of donuts sold and x represents the price. The slope of the regression equation indicates the rate of change in the number of donuts sold for a one unit change in the price. In this case, the slope is -12.00, which means that for every one dollar increase in price, the number of donuts sold decreases by 12.
