Answer: she sent 111 text messages in that month.

Step-by-step explanation:

The equation representing Ms. Thompson's total monthly call phone bill "b" is expressed as

b = 45.60 + 0.10t,

Where

"t" represents the number of text messages she made.

Therefore, the number of text messages that she made in a month in which the total charge was $56.70 is

56.7 = 45.60 + 0.10t

0.1t = 56.7 - 45.6

0.1t = 11.1

t = 11.1/0.1 = 111
