Trent plants a sunflower

Trent plants a sunflower that is 6 inches tall. The sunflower is expected to grow at an average rate of 1.5 inches per day during the next month.

A. Create an equation that Trent can use to find the number of days, x, it will take the sunflower to grow to a height of 45 inches.

B. How many days will it take the sunflower to grow to a height of 45 inches.

Part A
Create an equation.
It starts at 6 inches and grows 1.5 inches per day.
y = 1.5x + 6   {x is the number of days and y is the total height}

Part B
How many days to grow to 45 inches?
Substitute 45 in for y and solve for x:
45 = 1.5x + 6   {substituted 45 for y}
39 = 1.5x   {subtracted 6 from each side}
x = 26   {divided each side by 1.5}
It will take 26 days to reach 45 inches
