Answer: 35%
Step-by-step explanation:
- To start off divide 100% by the 20$ it began with, it should give you 5%
100/20 = 5
this means that every dollar is worth 5%
- now leaving that aside, subtract 20$ by 13$, it should give you 7$
2--13 = 7
the reason you do this is because since we're looking for the amount reducted, you have to subtract from the beginning amount.
- Finally, with the knowledge gathered, you multiply 5% by the 7$ that were deducted, it should give you 35%
7(5) = 35
The reason we did this is because every dollar is worth 5% and there were 7$ deducted, it results in 35% reduced.
