Carlos bought a video game. He made an initial payment of $75 to the store, and he will pay $5 each month until the game is paid off. Which equation represents the relationship between m, the number of monthly payments Carlos has made, and t, the total amount that Carlos has paid the store?

t = 75m + 80
t = 5m + 75
A student is ordering candy bars for a team fundraiser.
