Regina has $500 in a savings account. She wants to purchase a washer and dryer set for $1,600, and she takes out an interest-free loan at
the store. Her monthly payment is $134. Regina saves an extra $75 each month in addition to her loan payments. What system of
equations could Regina use to determine when she will have enough money to completely pay for the washer and dryer set?
A. y= 134x + 500
y= 1,600 - 100%

B. y= 75x + 500
y= 1,600 - 134x

c. y= 500x + 75
y = 1,600 - 134x

D. y=1,600x + 134
y = 75x -500

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers.firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?
