Suppose a taco costs $4 and a burrito costs $2. moreover, this mexican restaurant has a special deal. after you've bought 6 burritos, you can buy each extra burrito for $1.50. assume that tacos are on the vertical axis and burritos on the horizontal axis. what is the marginal rate of transformation (mrtbt) when 8 burritos are purchased?

Hilary works at klothes kloset. she quickly the customers, and her cash drawer is always correct at the end of her shift. however, she never tries to "upsell" the customers (for example, by asking if they would like to purchase earrings to go with the shirt they chose or by suggesting a purse that matches the shoes they are buying). give hilary some constructive feedback on her performance.
