Answer:

$\boxed {\boxed {\sf Haircut: \$47 \ and \ Color: \$ 100}}$

Step-by-step explanation:

Let's set up a system of equations. (1 equation for yesterday and 1 for today).

Let h = haircut and c= color

$2h+1c= 194$ (Yesterday: 2 haircuts and 1 color for $194).

$2h+4c= 494$ (Today: 2 haircuts and 4 colors for $494).

Notice that both equations have a 2h. If we subtract the two equations, the 2h will cancel and leave us with one variable, c.

$\ \ (2h+1c=194) \\- (2h+4c=494)$

$\ \ 1c=194 \\- (4c=494)$

$-3c= -300$

Since we are solving for c, we must isolate the variable. It is being multiplied by -3. The inverse of multiplication is division. Divide both sides by -3.

$-3c/-3=-300/-3 \\c= -300/-3 \\c=100$
