Tom just received a credit card with an introductory apr of 0% for nine months and a credit limit of $500. the apr for purchases after the introductory period is 19.9%. the penalty apr is 24.9% and the apr for cash advances is 20.4%. tom uses his card at the mall and spends $360. if tom wants to have a balance of $0 before his introductory period expires, what monthly payments should he make?

Given:
0% - APR for nine months
$500 - credit limit
19.9% - APR after nine months
24.9% - APR penalty
20.4% - APR for cash advance

Tom spends $360. He wants to have a zero balance before his introductory period expires.

Tom must divide his spending by 9 months.

$360 ÷ 9 mos = $40

Tom should make a monthly payment of $40 for nine months to achieve a balance of zero before the introductory period expires.

The monthly payment Tom must make is $40

Step-by-step explanation:

The steps taken in solving the problem is shown below

Tom received a credit card with an APR =0%

The credit limit is = $500

The APT for purchases after the introductory period is = 19.9%

The APR penalty is = 24.9%

APR cash advances = 20.4%

Tom spends $360 with his card at the mall, for which  He wants his balance to be zero  before his introductory period elapses.

For a 9 months period, Tom must divide his spending's  /expenses

Therefore

$360 ÷ 9 months gives  = $40

x=0,3π/2,π

Step-by-step explanation:

Given

sin^2  x+sin⁡x=0

sin x is a common factor

so,

sin⁡x (sin⁡x+1)=0

We can put both factors one by one equal to zero

sin⁡x=0

x=  sin^(-1)⁡0

sin⁡x  is zero at 0 and π

x=0,π

sin⁡x+1=0

sin⁡x= -1

x=  sin^(-1)⁡(-1)

sin is -1 for 3π/2

So,

x=3π/2

So,

x=0,3π/2,π
