The constant in an algebraic expression is the only term that cannot be changed.
Terms with variables are not constants as their values can changed as the variables change.
Our equation is 3m+7
M is a variable. Therefore the term '3m' is not the constant.
This leaves us with the term '7'. There is no variable present in this term.
'7' is the constant in this equation.

Answer:The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.
