Answer:

For A

For grace the x would be the number 18

y = 1000 (18) + 7600

y= 18000 = 7600

and that would mean y = 25600

Now for Claire you have to use the method rise over run

The equation for claire is y=800x + 7600  

11600-10000/3=800

---------------------------------------

y= 800(18) + 7600

y= 14,400 + 7600

y= 22,000

This shows that Claire would have $22,000 when shes 18 and Grace would have $25,600 when she is 18.
