B for sure!!!!!!!!!!!!!!!!!!!
B as if you plug the co-ordinates into the equation and it equals 10: (3x4)-2= 12-2 =10
A doesn't work as the answer is 20
C doesn't work as the answer is 14
D doesn't work as the answer is -20
I believe the answer is c, TSR
Tax is: $10* (7/100)= $0.70.
$10+ $0.70= $10.70
The final answer is $10.70~
