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:

35\cdot0.5=17.5

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 35+17.5 = 52.5

So four pairs cost 52.5\cdot2 = 105

However, there is a tax of 6.5%

So we can multiply 105 by 1.065 to get the cost after tax.

105\cdot1.065=111.825

This simplifies down to 111.83.

Hope this helped!

Margaret is saving money for her summer vacation. She calculates that her starting amount is 0.4% of the total amount she wants
garri49 [273]

0.4% can be written as 0.004 in decimal.

Step-by-step explanation:

Let the total amount she wants to save be 'a'

Starting amount = 0.4% of the total amount

= 0.4% of a

= (0.4/100) a

0.4% = 0.4/100

= 0.004

0.4% can be written as 0.004 in decimal.
