$108

Explanation:

First you need to find what 40% of 180 is.
To find 10% of a number you have to move the decimal place back by one.
For example, 10% of 120.0 would be 12.00 (12).
Using this technique we find that 10% of 180 is 18.

now we times 18 by 4 to create 40% of the cost.

18 xx 4= 72

Now minus 72 from 180 (the total cost of the bike).

180-72= $108
So , this means Jenny paid $108 for her bike.
