Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bush has. She finds a linear relationship that can be modeled by the equation y=1.345x+4

. When will Olivia only have 4 blooms?

A When she adds no fertilizer.When she adds no fertilizer.
B Every bush will only have 4 blooms.Every bush will only have 4 blooms.
C When she only adds 1 ounce of fertilizer.When she only adds 1 ounce of fertilizer.
D It is not possible for her to only have 4 blooms.

To find out when Olivia will only have 4 blooms, we need to find the value of x when y = 4 in the equation y = 1.345x + 4.

Substituting y = 4 in the equation, we have 4 = 1.345x + 4.

Simplifying the equation, we have 1.345x = 0.

Dividing both sides of the equation by 1.345, we have x = 0.

So, when Olivia adds no fertilizer (x = 0), she will only have 4 blooms.

Therefore, the correct answer is:

A When she adds no fertilizer.
