Linette invested $20,000 at Wells-Fargo Bank at an interest rate of 5% a year compounded semi-annually over 4 years. She then invested $20,000 at Chase Bank at an interest rate of 5% compounded continuously over 4 years. Which bank gave her the better return of her investment, and by about how much?

126-(x/2)=y

Step-by-step explanation:

We have that x represents weight check

If the dog is losing 4 ounces per week he will lose 8 ounces every weight check it is equivalent to 1/2 pound every weight check

If x is the checks 1/2*x represents the total of pounds the dog is losing depending the total checks

In one equation, we know dog´s first weight= 126 pounds

Then the equation is:

126-1/2*x=y

126-x/2=y

"y" being the final max weight depending on total weight checks
