Yesterday I went to lunch with a friend. I bought 3 tacos and Chips and salsa for $2. She bought 4 tacos. Together we spent a total of $23. Write an equation to determine how much one taco costs.

each taco costs $3

t = (23-2)➗(4+7)

Step-by-step explanation:

t represents the cost of one taco

23 is the total cost and 2 is the cost of the salse, the 3 is how many tacos you got and the 4 is how many your friend got.    

t = (23-2)➗(3+4)    First solve what‘s in the brackets  

t = 21 ➗ 7              Then divide whats left    

t = 3                         That gives you answer of 3 per taco
