Answer:
(C) $111.83
Step-by-step explanation:
If Sonya buys four pairs of shoes, each on a buy one get one 50% off, that means that we can find the value if she bought ONE deal of buy one get 50% off one, then multiply that by 2 (as if you do the deal, you are paying for two.)
The shoe costs $35, and if we have a 50% discount on it:
So the cost of the shoe ON DISCOUNT is 17.50, however the first pair still stays the same.
So the cost of two pairs of shoes using the discount is
So four pairs cost
However, there is a tax of 6.5%
So we can multiply 105 by 1.065 to get the cost after tax.
This simplifies down to 111.83.
Hope this helped!
Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:
To get cost per kilogram, we divide the cost given by the kg given.
1. We need to divide 4 by 1.5 to get cost per kilogram.
Cost/Kg =
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg =
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg =
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg =
As we can see, the second option costs the least per kilogram.
Answer:
= One-half more than three-fourths of a number
= Three-fourths minus one-half of a number
= three-fourths minus the sum of a number and one-half
Step-by-step explanation:
Suppose x be an unknown number.
∵ 3/4th of a number =
= One-half more than three-fourths of a number
Now, half of a number =
= Three-fourths minus one-half of a number
Sum of a number and one-half =
= three-fourths minus the sum of a number and one-half
