Anthony bought a new computer. He made an initial payment of $100 to the store, and he will pay $25 each month until the computer is paid off. Which equation represents the relationship between m, the number of monthly payments Anthony has made, and t, the total amount that Anthony has paid the store?

t = 25m + 100

t = 25m - 100

t = 100m - 25

t = 100m + 25
