25 = 1/4n - 3
n = 112
Steps:
25 = 1/4n - 3
+ 3 +3
28 = 1/4n
now multiply by 4 or (4/1), combine like terms and simplify 4 * 1/4n.
4 * 28 = 4 * 1/4n
112 = n

Write the equation:
You buy 3 books that each cost the same amount and a magazine, totaling $55.99. The magazine cost $1.99. How much does each book cost?
Solve for 100 BONUS points.
3b + 1.99 = 55.99
BONUS: 3b + 1.99 = 55.99
-1.99 -1.99
3b = 54.00
3b/3 = 54.00/3
b = 18 Each book costs $18.00.
