Leighanne is saving at a faster rate than Martin.

Answer 1

Answer:

Leighanne is saving at a faster rate than Martin.

Step-by-step explanation:

We see from the graph that Leighanne started out at (0, 15); this means she began with $15.

At 1 week, Leighanne has $60; this means she is saving 60-15 = $45 each week.

Martin goes from week 1 at $65 to week 3 at $145; this means he has saved $145-$65 = $80 in 2 weeks, or 80/2 = $40 per week.

This means he started with $65-$40 = $25.

Thus the only correct statement is that Leighanne is saving at a faster rate than Martin.
