A music store sold 103 CDs and 102 CD players. If each CD costs $12 and each cd player costs $35, what was the stores total earnings?

Lets solve this!

We need to multiply the cost and the amount of sold CD's and CD players. After multiplying, you need to add the answer to get the total earnings.

Lets form this into statements

Number of sold CD's = 103

Number of sold CD players = 102

Cost of each CD = $12

Cost of each CD player = $35

Total earnings:

CD = 103 × 12 = 1560

CD players = 102 × 35 = 3570

Now, to find the total earning, add 1560 and 3570 ---

1560 + 3570 = 5130.

The total earning of the store is $5130.

Hope I helped (:

Have a great day!

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
