4. (a) a woman whose annual salary is $55,400 gets a 4% raise. what is her new
annual salary?

$57616

Step-by-step explanation:

When you have a percent value, you may change it into a decimal by moving the decimal place 2 to the left. This means that 4% turned into a decimal is 0.04. In order to solve this problem we must multiply 55,400 by 0.04. When we do this, we get 2216. Last but not least, we must add 55,400 and 2216 together to get her salary with the raise.

Hope this helps -Cam ♡

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55
