questions about orders@prices

what is the calculation behind the screen? When I did prices@orders, I get an array with several elements instead of one. However, prices is only a flattened array.

Hi yige yang, I just went through this section, and noticed that your order set is incorrect. it should be orders@prices. The calculation of this is a whole mess of fast food orders (let's look back at the taco experiment.)

Array 1 [2, 0, 0, 0] ~This two represents tacos each a $1.50, which totals the first answer of the total array of $3. Array 2 [4, 1, 2, 2,] ~ This represents the 4 tacos 1 burrito, 2 horchatas and 2 mexican cokes. which equal the total of $20.50(so then this Array math is 1.50*4, 1 burrito *8 dollars, 2*1.25 horchatas, and 2*2 mexican cokes) Array 3 [0,1,0,1,]- 0 tacos, 1 burrito * 8 dollars, 0 horchatas, 1*2) equals $10. Array 4 [6. 0, 1, 2] - 6*1.50 tacos, 0 burritos, 1*1.25 horchatas, 2*2 mexican cokes for a total of 12.25

Hope this helps!
