part B 29.67

Step-by-step explanation:

first you multiply $39.99 dollars and  0.30 = $11.9970 you round this to $12.00

then you apply the discount $39.99 - $12.00  = 27.99  

next you must multiply 27.99*0.06 =1.6794 and round to 1.68 to get tax

lastly you add $27.99 and 1.68 to get a total of $29.67 for the headphones

$39.99  * 0.30 = $11.9970 round to $12.00

$39.99 -$12.00= $27.99 price after discount

$27.99 * 0.06= $1.6794 round to $1.68

$27.99 + $1.68 = $29.67 total amount Dalton paid for the headphones

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
