Answer:
x = 1 and y = 5
Step-by-step explanation:
Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.
Answer:
The amount of tax is $14.37 and the tax rate percentage is 12.18%
Step-by-step explanation:
Find the amount of tax by finding the difference between the cost and selling price:
132.37 - 118
= 14.37
Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:
(14.37/118) x 100
= 12.18
The amount of tax is $14.37 and the tax rate percentage is 12.18%
