Question

Eric ordered 6 tacos and 1 large pop. The large pop costs $2.00 and the total cost of his order was$21.50. Write and solve an equation to determine the cost of each taco.
Define a variable:
Write an equation:
1. Answer: 6x + $2=$21.50
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.
