81=81•2/2=162/2
81 1/2=162/2+1/2
=163/2
So 81 1/2=163/2=81.5
1X+8X=90
9X=90
X=10
so one of them is 10 and the other one is 8 times 10 which become 80
69. The jacket is said to have an original price of 45.00 dollars.
Now, is was given a 25% off.
Solve for the final cost of the jacket after the discount is applied.
=> 25% = 25% / 100% = 0.25
=> 45.00 * .25 = 11.25 dollars is the discount.
Now, let’s subtract the value of 25% by the original value.
=> 45 – 11.25 = 33.75 dollars.
This is now the costs of the jacket after the discount is applied.
