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

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
