Question

Write and simplify the equation you would use to solve the problem below.

Jack buys a magic bean plant that is 6 inches tall and grows several inches a day. After 48 days the bean plant is 198 inches tall. How many inches does the bean plant grow each day?

Answer 1

original height + (growth per day)(number of days) = current height (if you don't understand this please let me know)

since we don't know how many inches the bean grows per day, we can use a variable such as x to represent "growth per day". substitute "x" for "growth per day" and fill in the other quantities from the problem. this will give you the equation, then simplify by combining like terms
