The values of the following finite geometric series represent the rise in water depth each year for a lake near Sean's house, in inches. How much has the lake risen in total?
3+ 4.5+ 6.75 + ... + 34.171875

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

because that’s us why
