Answer:
The Tax is $12.39 and the Tip is $28.50.
Step-by-step explanation
For the tax:
137.62->100%
x->9%
100*x=137.62*9
100x=1238.59
Divide both sides by 100 and you get $12.39.
You now need to add the 12.39 to 137.62 and you get 150.01.
For the tip:
150.01->100%
x->19%
100*x=150.01*19
x=28.50
So the total price, including tax and tip is $178.51.
