Mira buys a gold ring for ₹ $8740$ inclusive of $15\%$ tax. The ring was sold at a discount of $5\%$ .
Sloan [31]

The marked price of the ring given the cost as 8740 inclusive of 15% tax and discount of 5% is $7,283.3.

<h3>Marked price</h3>

  • Cost of the gold ring = $8740
  • Tax = 15%
  • Discount = 5%
  • Marked price = x

8740 = x + (15% of x) + (5% of x)

8740 = x + (0.15x) + (0.05x)

8740 = x + 0.15x + 0.05x

8740 = 1.20x

x = 8740 / 1.20

x = 7283.33333333333

Approximately,

x = $7,283.3

stepan [7]

Answer: The correct answer is 94 cm.

Step-by-step explanation:

wingspan         length

60 meters        70.5 m

----------------- = ----------------

80 cm                   x

Cross multiply

(60 m)x = (70.5 m)(80 cm)

Solve for x by dividing both sides of equation by 60 m:

x = (70.5 m)(80 cm) / (60 m) = 94 cm

The length of the model is 94 cm.

Please simplify this with explanation <br> -10+4(2b+2)=
AleksandrR [38]

Answer:

2(4b-1)

Step-by-step explanation:

1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2

Answer to first step: -10+8b+8

2. Add the numbers. It should be -10 + 8 which would give you -2

Answer to second step: -2 + 8b

3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2

Answer to third step: 8b - 2

4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Hope this helped!
