Shaw · Answer 1

A:

Coefficient is a number multiplied by an unknown variable. Both 10.50 and 15 are coefficients

B:

You plug in the given values into the provided formula.

10.50 (37) + 15 (12) + 50

388.50 + 180 + 50 = 618.50

C:

Only the coefficient 10.50 would change to 11.25, because this is a representation of the dollar amount per hour that she works.
