Write a function that represents Jessica’s savings.

Question

On March 1st, 2012 of her freshman year, Jessica started working 2 jobs after school. (She is working in her parents’ store and does not need working papers.) She works the same number of hours every week. Jessica decided to save all her money to purchase a new car after she graduates.

After five weeks of work, she had $1,570 saved. After ten weeks, she saved $2,453.  

Write a function that represents Jessica’s savings. 

Answer 1

the slope is M= (2453 - 1570)/(10-5) = 883/5 = 176.60 per week.

B = y - mx = 1570 - 176.60*5 = 687

y = 176.6*x + 687 where x is the # of weeks
