Ms. Thompson's total monthly call phone bill "b" can be found using the equation b = 45.60 + 0.10t, where "t" represents the number of text messages she made. Find the number of text messages she made in a month in which the total charge was $56.70

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

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer is 1030 it's very simple math.
