Answer:

Grace should use her phone for 58 minutes to maintain an average of 55 minutes.

Step-by-step explanation:

Usage of first month = 43 minutes

Second month = 62 minutes

Third Minutes = 57 minutes

Let, the usage of fourth month =  k minutes

Mean of the data = 5 minutes

Now, Average of a Data =  \frac{\textrm{Sumof observations}}{\textrm{Total number of observations}}

⇒55 = \frac{43 + 62 + 57 + k}{4}

or, 55  x 4 = 162 + k

⇒    220 - 162  = k

or, k = 58 minutes

So, Grace should use her phone for 58 minutes to maintain an average of 55 minutes.
