Ellen paid $20 to download 25 songs. She stated that this is a rate of $1.25 per download. Explain whether or not Ellen's statement is true

Sagot :

Answer:

it is false

Step-by-step explanation:

if she paid 25 for 20 songs, it would be true. however it is 20 for 25. to find the cost of each, divide 20 by 25.

20/25=0.80

each download cost 80 cents

Ellen's statement is not true because the rate is actually 0.8 dollars per download and not $1.25 per download.

She downloaded 25 songs for $20 . Therefore, let's find the rate and know whether she calculated the rate rightly.

rate = cost in dollars / numbers of song downloaded

cost($) = $20

number of song downloaded = 25

Therefore,

rate = 20 / 25

rate = 0.8 dollars per download

The actual rate is 0.8 dollars per download. This means Ellen's was wrong to state that the rate was $1.25 per download.
