Answer:
(C) -26%
Step-by-step 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%
