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

The quantitative relation between two amounts showing the number of times one value contains or it’s contained within the other.
The question is:
19. if g(x) = 3 + x + e^x, find the inverse function of g (4).
Solution:
1) Put the equation as y = 3 + x + e^x
2) Solve for x = > x + e^x = y - 3
3) switch x and y => y + e^y = x - 3
4) y is the inverse
5) find y for the value requested (x = 4)
=> y + e^y = 4 - 3
=> y + e^y = 1
the solution is y = 0 because 0 + e^0 = 0 + 1 = 1.
