Several items in a store are on sale. Complete the table with the correct prices.
jarptica [38.1K]

Answer:

1. $48

2.$49

3.$91

4.$12

Step-by-step explanation:

For 1 and 2

To find the sale price, you find out how much is the percentage of the original price. Example :

(20/100)/60 = $12

So $12 is the discount

thus sales price will be $60-$12=$48

Same thing for no.2, find the amount of the percentage and subtract it from the original price

For 3 and 4

To find the original price

1. Subtract the percentage from 100%

2. Multiply the sales price by 100

3. Divide the ans from no.2 by ans from no.1

Example :

100%-40%=60%

$54.60×100=5460

$5460÷60%= $91 (original price)

Same thing for no.4

Hope this helps haha

Answer:  C) 4.20

Explanation:

Multiply each value with its corresponding frequency:

  • 1*450 = 450
  • 10*35 = 350
  • 50*10 = 500
  • 100*4 = 400
  • 400*1 = 400

Add up the products

450+350+500+400+400 = 2100

Then divide this over the total frequency (450+35+10+4+1 = 500)

So we get 2100/500 = 4.20 as the expected value.
