Question

A music store sold 10^3 CDs and 10^2 CDs players.If each CD costs $12 and each CD player costs $35,what was the store's total earnings

Answer 1

10^3= 1000
10^2= 100

multiply  1000  x $12= $12000 for CD's
multiply 100  x $35= $3500 for the CD players
now add the two totals
$12000 + $3500 =$15500 earnings for the store

hope this helps

Answer 2

The store's total earnings if a music store sold 10^3 CDs and 10^2 CDs player is $15,500

The number of CDs sold by music store is 10³CDs

If each of the CDs cost $12, the cost of 10³ CDs is expressed as;

Cost of 1000 CDs = 12 * 1000 = $12000

Similarly,

The number of CDs players sold y music store is 10²CDs

If each of the CDs cost $35, the cost of 10² CDs is expressed as;

Cost of 100 CDs players= 35 * 100 = $3500

Total earning will be the sum of the amount earned on CDs and CDs player

Total earning = $12000 + $3500

Total earning = $15,500

Hence the store's total earnings if a music store sold 10^3 CDs and 10^2 CDs player is $15,500
