Jose starts with $250 and spends $25 a week. Martin starts with $30 and saves $30 a week. When do Jose and Martin have the

same amount of money? Use x for time and y for saving.

4 weeks, Jose and Martin will have the same amount of money in 4 weeks which is $150 each

Step-by-step explanation:

Jose:

y = - 25x + 250

Martin:

y=30x+30

Substitute x = 6 into the two equations

Jose:

y = - 25 (6) + 250

= - 150+250

y = 100

Martin:

y = 30 (6) + 30

=180+30

y = 2100

Substitute x=4 into the two equations

Jose:

y = - 25 (4) + 250

=-100+250

y = 150

Martin:

y = 30 (4) + 30

=120+30

y = 150
