Angela pays $393 in advance on her account at the athletic club. each time she uses the club, $5 is deducted from the account. write and equation in her account after x visits to the club. find the value remaining in the account after 18 visits.

y= 393- 5(x)    after 18 visits value remaining in her account is 303$

Step-by-step explanation:

let the amount in her account be y $

y= 393- 5(x)  where x is the number of visits.

after 18 visits y= 393- 5(18)= 393-90= $303

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.
