The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.
Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.
However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
Answer:
B.lightning striking a tree
Explanation:
The crowd dispersing in all directions is not a closed-loop by any means, and students jogging around an oval track as well is not a closed-loop, and also not a cross country run from one point to another. However, the lightning striking a tree is a closed loop that best models a circuit. And as lightning strikes the tree, like a closed circuit, tree catches the fire, or in circuitry words, the current is generated, and tree catches the fire due to it, just like bulb starts glowing.
