Answer and explanation:

The wrong step  <u>is changing the sign in step 2</u>

Such that; in step 1 the student had; (x + 6) and (x - 2)

In step 2, the student should have;

x + 6 = 0 and x - 2 = 0 instead of x - 6 = 0 and x + 2 = 0

Step 3, will thus be;

x = -6 and x = 2

Answer:

The minimum number of daffodils in each bag have to be 12.

Step-by-step explanation:

Given:

Grant bought more than 120 flower bulbs to plant in his garden.

He bought 2 bags of tulip bulbs with 30 bulbs per bag.

He also bought 5 bags of daffodil bulbs.

To find:

Least number of daffodil bulbs that could be in each bag = ?

Solution:

So, we know that Grant has more than 120 total flowers in his garden which means he has a minimum of 120 flowers in his garden. So, for calculation we will consider the total number of flowers in his garden as 120.

But we need to find the minimum number of daffodils in each bag so that all the flowers add up to 120.

Let the number of daffodils in each bag be ‘x’.

So, from the given information we can form the following expression.

Tulips + daffodils =120

The number of tulip flowers are:

=2×30

=60

Therefore, total number of flowers:

60 + 5(x)=120

5(x)=120-60

5(x)=60

x=12

Hence the minimum number of daffodils in each bag have to be 12.
