If am wrong sorry
One can take the price of the item before the discount is applied and subtract that from the percentage off and get the cost of the item.
I find this is the most effective way.
another method could be if one turned the percentage into a decimal it could be subtracted from the cost of the item.
Answer:$13.50
Step-by-step explanation:
First thing you want to do is find what is 6% of 14.31. You can find this using your calculator and putting the percentage in decimal form then multiplying it by the given amount. 0.06 x 14.31 = ? And then you take that number and subtract it from 14.31.
From eqn 3,
2z = 10
z = 5
Substitute z = 5 into eqn 1&2
x + 2y + 5 = 9
x + 2y = 4
x - y + 3(5) = 13
x - y = -2
Eqn 1 - eqn 2:
x + 2y - (x - y) = 4 - (-2)
3y = 6
y = 2
Substitute y = 2 into eqn 1
x + 2(2) = 4
x = 0
Thus, x = 0, y = 2, z = 5 (option 3)
Answer:
