15% of 11.50 = 1.72 --> 11.50 - 1.725 = 9.77
9.77 - 1.50 = 8.27/2 = 4.14

Answer: ⇒ <u><em>=368</em></u>
Step-by-step explanation: ⇒ Multiply by the numbers. Product it's going to be multiply by the numbers, fractions, multiples, and factors. You can also remove parenthesis, this give us, 92*4=368. Hope this helps! Thanks!
