Iwant to know how to solve 3-3x6+2=

Parentheses
Exponents
Multiplication      Multiplication and division can both go first depending on         Division              which one comes first from left to right
Addition
Subtraction        Addition and subtraction can both go first depending on which                             one comes first from left to right

3 - 3 * 6 + 2  <---- Original
3 - 18 + 2    <-----First you multiply
-15 + 2  <----- Next you subtract
    -13   <----- Than you add, and you get your answer

Your answer : -13

Bank balance after 15 years is $950

Step-by-step explanation:

Step 1: Find the simple interest on the principal amount using the formula SI = PRT/100 where Principal (P) = $500, Rate of Interest (R) = 6% and Time(T) = 15 years

⇒ SI = 500 × 6 × 15/100 = $450

Step 2: Find total amount using the formula Amount = P + SI

⇒ Amount = 500 + 450 = $950
