A florist is creating centerpieces for an upcoming event later this evening. She has already been working for two hours and has
Kobotan [32]

Answer:

No inequality given but in my view answer is:

x ≥ 16

Step-by-step explanation:

Given that:

Total time = 6 hours

Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)

Time required for 1 centerpiece = 15 mins

We have to find inequality for x:

Number of centerpieces she makes = x

In 240 mins : 240/15 centerpieces can be made

                    = 16 centerpieces

If she works with the same speed or more efficiently the suitable inequality would be:

x ≥ 16

I hope it will help you!
