g100num [7]

Answer:

syd is 23 and dev is 69

Step-by-step explanation:

Tammy has a job that has a weekly salary of $1,200 but wants to switch a job that has a monthly salary of $11,700. How much more

iogann1982 [59]

Answer:

$1529.8

Step-by-step explanation:

Given:

Tammy has a job that has a weekly salary of $1,200.

But wants to switch a job that has a monthly salary of $11,700

Question asked:

How much more will she make per week if she switch to the new job?

Solution:

Monthly salary of a new job, she wants to switch = $11,700

Weekly salary of a new job, she wants to switch = ?

As we know : 1 month = 4.286 Weeks

Salary of 1 month for a new job, she wants to switch = $11,700

Salary of 4.286 Weeks for a new job, she wants to switch = $11,700

Salary of 1 Week for a new job, she wants to switch = $11700\div4.286=\$2729.81$

Now, we have to find that How much more she will make per week, if she switch to the new job.

More money she will make for a new job she wants o switch = Weekly salary for a new job, she wants to switch - Weekly salary of current job

More money she will make, for a new job = $2729.8 - $1200 = $1529.8

Therefore, she will make $1529.8 more per week if she switch to the new job.
