Howard planted a tree seed. After 2 years, the tree was 6 feet tall.Write and solve an equation to find how many inches the tree grows in 6 months.
y = 1/4x + 6
replace x with 6, you get 7.5 total feet, but if your just wondering how much more it grows, then omit the 6 in the equation, and you'll get 1.5 or 1&1/2feet.
