Nari says, “The sum of 10 and one-third of a number is 25.” She uses the bar model to write an equation to represent her statement.
A bar diagram. The top box contains 25. The bottom boxes contain 10 and one-third n.

Which equation can Nari write using the bar model?
25 = 10 + one-third n
10 = one-third n + 25
25 = 10 minus one-third
10 = one-third n minus 25
