Damon has 7 dimes and some nickels in his pocket, worth a total of $1.50. To find the number of nickels Damon has, a student wrote the equation 5n + 70 = 1.50. Complete the error in the student's equation. The error Damon made is that he represented the side of the equation in cents and the side of the equation in dollars.
