Yvonne continues to work full-time at her job while she attends college part-time. it takes 5 years for yvonne to complete the program, but when she does she is able to increase her salary from $37,000 per year to $45,000 per year. at this rate, yvonne will have recovered her college costs after 4.5 years. how much did it cost yvonne to go to college? a. $36,000 b. $45,000 c. $40,000 d. $32,000

We will not complicate the problem here. We know that Yvonnes current salary before she completes the program is $37000 per year. If she completes the program, she will earn $45000 per year. In 4.5 years with that rate, she can cover her program costs. This means 45000 x 4.5 = $202,500 is need in the 5 year program. If she earns 37000 x 5 = $185000 in the span of 5 years, we then subtract her earnings from the cost. We get 202500 - 185000 = $17500, which happens to be NOT in the choices.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
