On Part A you have to subtract $2.39-$1.99. Then in Part B you have to multiply $4.50 by 2. And then I think you have to add $3.79 when u are done multiplying.
The answer is B
because at first y was equal to 15 and x equaled to 3 the quotient of 15/3 = 5.
now the y is 60 so, 60/5 = 12
1) (3,2)
2) reflection across x-axis then 1 unit down
3) reflection across y-axis then 2 units left
3x+3y=-9
-3. -3
-9-3

y=-1x-3
