While Diane was visiting her sister in Kingwood, she bought a bunch of balloons that was marked down 20% from an original price
shepuryov [24]

Answer:

$4.34

Step-by-step explanation:

Given the information:

  • The original price: $5
  • Discount : 20%
  • Tax: 8.5%

We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:

= the original price (100% - discount rate)

= 5(100% -20%)

= $4

  • The tax amount she need to pay is:

= The actual price*tax rate

= $4*8.5%

= $0.34

=> the total cost of the bunch of balloons :

The actual price + tax price

= $4 + $0.34

= $4.34

Hope it will find you well.

Please Help Urgent <br><br> Find the m∠RLU.
maria [59]

The top right angle is given as 50 degrees.

Because the two sides are identical and Line LC is a bisector, the top left side angle must also be 50 degrees.

Set the given equation equal to 50 and solve:

6n -10 = 50

Add 10 to both sides:

6n = 60

Divide both sides by 6:

n = 60/6

n = 10

m∠RLU = 50

n = 10
