From triangle AED we can find the length of a side of ABCD

AD=(4^2+4^2)^(1/2)  (pythagorean theoerem)

AD=32^(1/2)

For similar reasons as applied to the triangle AC=(2AD^2)^(1/2)

AC=(2*32)^(1/2)

AC=64^(1/2)

Randy went to the store and brought a shirt that cost $42.00 before taxes and discount. The shirt was on sale for a discount of
gregori [183]

Answer:

Step-by-step explanation:

The 20% discount amounted to ...

  0.20 × $42.00 = $8.40

so the price before tax was ...

  $42.00 -8.40 = $33.60

The tax amount is 3% of this value, so is ...

  0.03 × $33.60 = $1.008 ≈ $1.01

So the total price paid for the shirt was ...

  $33.60 +1.01 = $34.61

Randy paid $34.61 for the shirt after discount and tax.

___

<em>Alternate solution</em>

You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...

  $42.00×0.80×1.03 = $34.608 ≈ $34.61

alisha [4.7K]

Answer

$266.66

Step-by-step explanation:

We have here ,

  • Principal = $200
  • Rate = 16%
  • Time = 10 months = 10/12 yrs.

We can use the formula of SI to calculate the SI . After adding it to principal we will get the amount .

⇒ SI = P × R × T / 100

⇒ SI = $ 200 × 16 × 10 / 12 × 100

⇒ SI = $ 26.66

Now Calculate amount as ,

⇒ A = SI + P

⇒ A = $ 200 + $ 26.66

⇒ A = $ 226.66
