Respuesta :

Jessica saves $4 more a week than Raphael. I took this quiz and it was correct.

Jessica and Raphael are saving money for concert tickets,

Red line in the graph shows that Jessica starts with the amount  $20. After 5 weeks, she caught up to Raphael, who has also  $70 after 5 weeks.

According to the question ,They will each have saved $70.Jessica is saves at a faster rate than Raphael.

The rate at which Jessica sum up her savings = $4 every week more than Raphael adds upto his savings

  • The formula for Jessica’s savings to be

         y = 10x + 20

         Jessica  saves at the rate of $10every week.

  • The formula for Raphael’s savings to be

         y = 6x +40

       Raphael’s saves at the rate of $6 every week.

Boths savings when gets equal we get,

      10x + 20 = 6x + 40         ∵now we substract  20 from both the side

      10x = 6x + 20                 ∵here we  subtract 6x from both the side

       4x = 20                         ∵From both the side, Divide by 4

        x = 5

Both of their savings will get Equal after 5 weeks.

After 5 weeks,

      Jessica will have saved

           y = 10×5 + 20  

           y = 50 + 20

           y = $70

Raphael who has saved $70 but Jessica saves at a faster rate of  $10every week than Raphael at the rate of $4 every week

Therefore, Given Red line in the graph shows that Jessica starts with the amount $20 and  After 5 weeks, she caught up to Raphael, who has also $70.
