Question

I would like to know the equation for:

Edward has $300 in his savings account and plans to save $20 every two weeks from his paycheque.

Denise has $175 in her account and plans on saving $35 every two weeks from her paycheque.

Answer

These equations have x as the number of paychecks.

Edward = $300 + $20x

Denise = $175 + $35x  

Answer 2

Edward has $300 in his savings account and plans to save $20 every two weeks from his paycheque.

E = 300 + 20t

Denise has $175 in her account and plans on saving $35 every two weeks from her paycheque.

D = 175 + 35t

t is a two-week period

Maybe you want to know in how many weeks E & D will have the same amount in savings?

300 + 20t = 175 + 35t

-15t = -125

t = 8 1/3

In 16 2/3 weeks they will have the same amount

I expected an integer for an answer

Maybe I asked the wrong question
