Of 520 cds in a store 50% are rap 30% are jazz and the rest are pop how many cds are pop
To find the number of pop CDs, we need to calculate the remaining percentage after subtracting the percentages of rap and jazz CDs.
Percentage of pop CDs = 100% - (50% + 30%) = 100% - 80% = 20%
To find the number of pop CDs out of the total 520 CDs:
Number of pop CDs = 20% of 520 CDs
Number of pop CDs = (20/100) * 520
Number of pop CDs = (0.2) * 520
Number of pop CDs = 104
Therefore, there are 104 pop CDs in the store.
To find out how many CDs are pop, we need to subtract the number of rap and jazz CDs from the total number of CDs.
1. Calculate the number of rap CDs:
Rap CDs = (50/100) * 520
= 0.5 * 520
= 260
2. Calculate the number of jazz CDs:
Jazz CDs = (30/100) * 520
= 0.3 * 520
= 156
3. Calculate the number of pop CDs:
Pop CDs = Total CDs - (Rap CDs + Jazz CDs)
= 520 - (260 + 156)
= 520 - 416
= 104
Therefore, there are 104 pop CDs in the store.
