An online music company offers 15 downloads for $19.75 and 40 downloads for $43.50. each price includes the same one-time registration fee. what is the cost of each download and the registration fee?

Let

x> the cost of registration fee

y> the cost of each download

we know that

19.75=x+15y> equation 1

43.50=x+40y > equation 2

Subtract equation 1 from equation 2

43.5-19.75=40y-15y

23.75=25y

y=23.75/25> y=$0.95

Find the value of x

19.75=x+15y> equation 1

19.75=x+15*0.95

x=19.75-14.25> x=$5.5

therefore

the answer is

the cost of registration fee is $5.5

the cost of each download is $0.95

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
