Mary and Mark are saving to buy new bikes. They both start with $20. If Mary saves $15 a week and Mark saves $20 a week, how much will each have saved in week 6? Make a table and graph to solve.
+367 I'm not going to make a talk or graph but I can give the functions for each person.
w= number of weeks they saved
Mary's total saved = 20+15w
Mark's total saved = 20+20w
You can use those equations to make points on your graph and substitute w with 6 and solve the equations.
Hope this helped.
+876 Mary and Mark are saving to buy new bikes. They both start with 20 dollars. If Mary saves 15 dollars a week and Mark saves 20 dollars a week, how much will each have saved in week 6? Make a table and graph to solve.
Let Mary = a
Let Mark = b
Let w = number of weeks
We know that: a=20+15w
b=20+20w
In 6 weeks, just plug in w=6.
A = 20 + 15*6 = 110
B = 20 + 20*6 = 140
Mary: 110 dollars
Mark: 140 dollars
