What was the original price if: after 10% discount it becomes $450?

Answers

Answer: Original Price=$450

Step-by-step explanation:

Price post discount=$450

Discount=10%

Let the original price be x

Given x - 10% of x=450

$x-(10)/(100)* x$

$(100x-10x)/(100)$ =450

$(90x)/(100)$ =450

x= $(100*450)/(90)$

On solving

x=500$

The original price =500$

The original price before the 10% discount was about $500.

What is the original price?

To know the original price before the discount, one can use the following formula:

Original Price = Discounted Price / (1 - Discount Percentage)

So, the discounted price is $450, and the discount percentage is 10%.

To calculate the original price:

Original Price = $450 / (1 - 0.10)

= $450 / 0.90

- $500

Therefore, the original price before the 10% discount was about $500.

A group of 10 friends had lunch together at a restaurant. The meal cost a total of $99.50, including a 15% tip. How much was the total bill for lunch before the tip?

Answers

Cost of meal before tip + 15% = $99.50

Adding 15% is equal to multiplying by 1.15

Cost of meal before tip x 1.15 = 99.5

This can be rearranged to give;

Cost of meal before tip = $(99.5)/(1.15)$

Cost of meal before tip = $86.52

each meal was $9.95 a peice aND EACH HAD TO pay $1.50 on the tip

Step-by-step explanation:

8 out of 21 instruments in the band are woodwind. if there are 63 instruments in the band, how many more are not woodwinds than woodwinds?

Answers

Answer:

15 more are not woodwinds than woodwinds

Step-by-step explanation:

If there are 8woodwinds out of 21instruments, to know the number of woodwinds when we have 63instruments can be gotten as shown below;

8woodwinds = 21instruments

x woodwinds = 63instruments

Cross multiplying we will have;

x woodwinds × 21instruments = 8 woodwinds × 63instruments

x woodwinds = 8woodwimds × 63instruments/ 21instruments

x = 8×63/21

x = 24

This shows that there will be 24 woodwinds if there are 63 instruments

If there are 24woodwinds, number of those not woodwinds will be;

63-24 = 39

Therefore we have 24woodwinds and 39 that are not woodwinds.

To know how many more instruments that are not woodwinds than woodwinds, we will take the difference between those not woodwinds and those of woodwinds to give;

39-24 = 15

This shows 15 more are not woodwinds than woodwinds

Well21-8= 1363-21=4242-21=2113*2=26 tThere is 26 non woodwind instruments
