Taco Bell. Assume the price elasticity of tacos is 1.13, and the current price is $0.99. If we sell an average of 220/day, how will sales change if the prices goes up to $1.09? What will happen to total revenue? Our other product, burritos, has a current price of $1.29 and we sell, on average, 190/day. If we drop the price to $1.19 and then sell 224/day, what can we infer about price elasticity? Compare the price elasticity of both products and recommend a pricing strategy for each.
