Answer:

(C) -26%

Explanation:

Initial quantity of pizzas demanded = 10,000 slices

New quantity of pizzas demanded = 7,400 slices

Change in quantity of pizzas demanded = new quantity demanded - initial quantity demanded = 7,400 - 10,000 = -2,600 slices

Percentage change in quantity demanded = (change in quantity of pizzas demanded ÷ initial quantity of pizzas demanded) × 100 = (-2600 ÷ 10,000) × 100 = -0.26 × 100 = -26%
