Answer:
6 packages of hot dogs and 6 packages of buns
Explanation:
The indifference curves follow the 45-degree so the ratio for the hot dog:bun will be 1:1. Each package of hot dog gives 8 hot dogs while each package of the bun gives 8 hot dog buns. The ratio of hot dog package: buns package that Sue needs will be:
(number of hot dogs every package)/ (number of buns every package) * (ratio of hot dog : bun)
8/8 * 1/1= 1
The optimal choice package ratio is 1:1, then the amount of food Sue can buy will be: 48$/ (1*$5 + 1*$3)= $48/$8= 6 package.
The optimal choice is 6 packages of hot dogs and 6 packages of buns

One receptor is touchy to the green, another to the blue and a third to the red.
