Money spent + money left over = total money
money spent + 9 = 30
We don't know the price of each shirt, so let x = price of 1 shirt.

She spent 3x.
3x + 9 = 30

Answer:
C
Step-by-step explanation:
to evaluate substitute x = 0 and x = 1 into f(x)
note that 
= 1

Answer: 6x + $2= $21.50
Step-by-step explanation:
To make an equation first we are going to give the cost of each taco the variable x since we don't know what it is. Then we will combine 6 multiplied by x to get 6x and add it to $2 to get $21.50 so the equation will be 6x + $2= $21.50. First we subtract 2 from both sides of the equation which makes the equation become 6x= $19.50. Then we divide both sides of the equation by 6 and get x=$3.25. This means that each taco cost $3.25.
