Question

Connie and Chris are saving money to go to a concert. Connie has $9 and saves $6 per week.

Connie wrote an equation to determine how much she saves in a given week.

y=6x+9

Chris has $27 and saves $3 per week.

Chris made a graph to show how much he saves in a given week.

How many weeks will it take Connie and Chris to save the same amount of money?

Answer 1

Chris= $27 +3 30$
Connie= 9$ + 6= 15$
Chris= 30$ + 3 = 33$
Connie 15$ + 6 = 21$
Chris= 33$ + 3= 36$
Connie 21$ + 6 = 27$
Chris= 36$ + 3 = 39$
Connie= 27$ + 6 = 33$
Chris = 39$ + 3 42$
Connie 33 + 6= 39$
Chris= 42 + 3= 45$
and Connie = 39 + 6= 45$

And that took 6 weeks
