Mark is online buying songs to download to his smart phone. He has a $20 gift card. He sees that there is a one time fee of $10 to sign up. Then each song cost $1.99. Write the any quality that models the situation above.

(no random links please)

1.99x +10 < 20

Step-by-step explanation:

x = the number of songs

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
