Answer:
7%
Step-by-step explanation:
The additional tax is $0.42, we just have to find how much percent the tax ($0.42) is of the original cost ($6.00).
To do this, we can use the following formula:
Where x is the part (in this case, the tax ($0.42)), y is the whole (in this case, the original cost ($6.00)), and p being the percent (the tax rate in this case). We can replace the values in:
We can cross multiply and simplify to find the tax rate:
We're not done yet! We still need to turn it to percent. But we can do this by just multiplying our result by 100:
Place the percent sign and we are done.
Hope this helps.
