5 parts of water plus 2 parts of vinegar.
1 part of water = (2/5) parts of vinegar
= 0.40 parts of vinegar.
So Tim mixed 0.40 parts of vinegar with each (1) part of water.
Multiply 4.50 by 0.07
4.50*0.07 = 0.315
Then the sales tax is about $0.32.
You can also do it mentally. Moving the decimal point in 4.50 once to the left gives you 10% of the original amount, 0.45. Move it again to get 1% of the price, 0.045. Then multiply this by 7 to get 7%.
