Mrs. chang spent $44 for a movie ticket and snack for each of her 4 children. each snack cost $3.50.each snack cost $3.50.each movie ticket cost the same amount. one of mrs. changs children wrote the incorrect equation to find x, the cost in dollars, of each movie ticket.4x 3.50=44. explain why this equation is incorrect and write the right equation. example-2x-9=90

4x + 3.50 = 44. this equation is wrong because 3.50 is only good for 1 child. there are 4 children so, 3.50 must be multiplied by 4.

Correct equation is:  4x + 14 = 44   where 14 = 4 * 3.50

let x be the cost of the movie ticket.

number of children = 4
total cost of movie tickets = 4x
total cost of snacks = 4 (3.50)
total cost = 44

TC of movie tickets + TC of snacks = 44
4x + 4(3.5) = 44
4x + 14 = 44
4x = 44 - 14
4x = 30
4x / 4 = 30 / 4
x = 7.50 cost of movie ticket
