Answer: $96.44 would be your total after adding all of the tax.
Step-by-step explanation: How I find percentages is by putting them into fractions.
8.25/100 next to ?/75.50
If you put these fractions next to each other written down, with 8.25 over 100 and the unknown percent above the 75.50, you can then multiply 8.25 and 75.50.
8.25x75.50=622.875
next you divide 622.875 by 100
622.875/100=6.22875
you will need to round up at the hundreths spot. So the amount of tax you would pay is $6.23
Next you know that you need to find 18 percent of all of that so now you need to add the 6.23 and 75.50
6.23+75.50=81.73
now find 18 percent of 81.73
18/100 ?/81.73
multiply 18 and 81.73
18x81.73=1,471.14
divide
1,471.14/100=14.7114
round to the nearest hundreth
14.71
next add 14.71 to 81.73
14.71+81.73=96.44
So 96.44 is your total.
