Amusic store has sold 3/5 of their hip-hop cds, but 10 were returned. now the store has 62 hip-hop cds, how many hip-hop cds did they originally have?

130

Step-by-step explanation:

Let x be the original number of hip- hop CDs in the music store.

Given : A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.

i.e. The number of hip- hop CDs in the store  will be :

Original No. of CDs - CDs sold + CDs Returned

If  the store has 62 Hip-Hop CDs now , then required euation will be :-

Subtract 10 from both sides , we get

Hence, the number of CDs they originally have = 130

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!
