If, in equilibrium, the cross-price elasticity between airline tickets and gasoline is 2.2; when the price of the gasoline increases by 4%, the quantity demanded of airline tickets increases by nothing% (enter your response rounded to two decimal places).

8.8%

Step-by-step explanation:

Given that,

Cross-price elasticity between airline tickets and gasoline = 2.2

Price of the gasoline increases by 4%.

Therefore,

Cross-price elasticity  = Percentage change in the quantity demanded of airline tickets ÷ Percentage change in the price of gasoline

2.2 = Percentage change in the quantity demanded of airline tickets ÷ 4%

2.2 × 4 = Percentage change in the quantity demanded of airline tickets

8.8% = Percentage change in the quantity demanded of airline tickets

good luck!

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
