. For the 8th grade trip, each student is given $19 for food. This covers the cost of 2 meals at x dollars each plus $7 worth of snacks. Write the two-step equation to find how much money the school expects each student will spend per meal.
Please format your question properly
Thank you for formatting correctly,
x is the cost of one meal if I am not mistaken. So, 2x will be the cost of 2 meals. 7 dollars for snacks, and the total is 19.
2x + 7 = 19
subtract 7 from both side of the equation
2x = 12
divide 2 from both sides
x = 6
Each meal costs 6 dollars
