The weight of gemstones, such as diamonds, rubies, and emeralds, is measured in carats. A carat is a unit of measure equal to 20

Alexxx [7]

We are told in the question that 1 carat is equal to 200 mg.

The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

$\frac{200mg}{1 carat}* \frac{44.5 carats}{1}=8,900 mg$

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

$\frac{8,900mg}{1000}=8.9grams$

Now we know that the weight of the Hope Diamond is equal to 8.9 grams.

The cost of a car battery costs $35 wholesale for the automotive store to buy, but they need to markup the cost 40% for the reta

lara31 [8.8K]

Answer:

The markup amount is $14 and the retail price is $49.

Step-by-step explanation:

You can use the following formula to find the retail price with the information provided:

Retail price=Cost*(100%+markup %)

Cost=35

Markup %= 40%

Now, you can replace the values in the formula:

Retail price=35*(140%)

Retail price=49

Now, you can subtract the cost from the retail price to find the markup amount:

49-35=14

According to this, the answer is that the markup amount is $14 and the retail price is $49.

Answer:

The required number of plants is 10.

Step-by-step explanation:

Nursery P charges $15 per plant plus a $50 delivery fee on any order. Nursery Q charges $20 per plant and no delivery fee.

If x number of plants that must be delivered for the total cost to be the same at both nurseries, then

15x + 50 = 20x

⇒ 5x = 50

⇒ x = 10

Therefore, the required number of plants is 10. (Answer)
