Remember to use PEMDAS (Parentheses, Exponents, Multiplication ⇔ Division, Addition ⇔ Subtraction)

(7 + 5) + 4 · 13 - 12   Add 7 and 5
   12 + 4 · 13 - 12      Multiply 4 and 13
     12 + 52 - 12        Add 12 and 52
         64 - 12            Subtract 12 from 64
             52

Answer:

$690.86

Step-by-step explanation:

100% from the original cost is: 2 x 863.57 = $1,727.14

40/100 = X/1727.14 (40 percent is what of 1,727.40) (%/100 = is/of)

(40 * 1,727.14) / 100 = $ 690.86
