Kyle is saving his money to buy a computer for $300. He has already saved $75 and plans to save an additional $22.50 each day. Write an equation for the number of days Kyle will need to save in order to buy the computer
The equation sums the amount Kyle currently has (75) with the amount he saves in d days (22.50d). It sets that total to 300, since Kyle hopes to save a total of $300 in d days.
