Okay! Assuming this only wants the tax that will be added to the total, multiply the decimal percent by the cost of the item.
7.5% = .075
14.80 * .075 = 1.11
1.11 of tax will be added onto the total cost.
The total cost would be 15.91, which you can get from adding 14.80 to 1.11 or by doing 14.80 * 1.075. Regardless, the answer to this question is 1.11.
1/2m-3/4n=16
1/2m-3/4(8)=16
1/2m-6=16
1/2m=22
m=44
I hope this helped!
Just do 4.5 x4.5 and get 20.25 then divide that by 55 and get the answer of 2.7 months. Hope this helps
