A pair of shirt is 99$ dollar and take 10% off how much will the shirt will be
99/100=0.99 (So 1% of 99 = 0.99) 0.99x10=9.9 (So 10% of 99 = 9.9) And here we are left with Hero's answer: 99-9.9=? Do the math...
I started off by moving the decimal one place to the left and then subtracting that from 99
Oh, and if the question is how much is one shirt, just divide the answer by two, your wording is a bit confusing toward the end...
