A music 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
kow [346]

Answer: 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

x-\dfrac{3}{5}x+10

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

x-\dfrac{3}{5}x+10=62

Subtract 10 from both sides , we get

x-\dfrac{3}{5}x=52

\Rightarrow\ \dfrac{5x-3x}{5}=52

\Rightarrow\ \dfrac{2x}{5}=52

\Rightarrow\ x=52\times\dfrac{5}{2}=130

Hence, the number of CDs they originally have = 130

Akimi4 [234]
Well, is namely their difference, so, let's first convert the mixed fractions to "improper", and subtract.

\bf \stackrel{mixed}{30\frac{1}{2}}\implies \cfrac{30\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{61}{2}}&#10;\\\\\\&#10;\stackrel{mixed}{100\frac{3}{4}}\implies \cfrac{100\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{403}{4}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{61}{2}-\cfrac{403}{4}\impliedby \textit{so our \underline{LCD is 4}}\implies \cfrac{(2\cdot 61)~-~(1\cdot 403)}{4}&#10;\\\\\\&#10;\cfrac{122-403}{4}\implies \cfrac{-281}{4}\implies -70\frac{1}{4}
