What is 1+1 if -1 is 2 which 1 is 0 so 2 is 1

0

Step-by-step explanation:

-1=2

1=0

2=1

0+0=0

 The equations are  A= 600 + 125w    and A = 1100 + 50w.  Look into the steps for more information.

Step-by-step explanation:

Zypel's situation can be represented by the equation,  A= 600 + 125w   where  A is the amount of money she will have after w weeks.

The same way we can represent Joshua's situation by the equation  

A = 1100 + 50w        where a is also the amount of money he will save after w weeks.

It says that there are 4 weeks in one month which means there will be 16 weeks in 4 months.

Now input 16 into the equations for w and solve for A.

A = 600 + 125(16)

A= 600 + 2000

A = 2600      

So Zypel will save $2600 in a 4 months

A = 1100 + 50(16)

A= 1100 +800

A= 1900  

So Zypel will save more than Joshua in four months.
