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.
