For his birthday, mr. moore and three of his friends went to a movie. they each got a ticket for $7.00 and the same snack from the concession stand. if mr. moore's mom paid $42 for the group's tickets and snacks, how much did each snack cost? the equation 4( + 7) = 42 represents the situation when represents the cost, in dollars, of one snack. write and solve an equation that tells how much the snacks cost.

Step-by-step explanation:

For his birthday, Mr. Moore and three of his friends went to a movie. This means that they are 4 persons

They each got a ticket for $7.00 and the same snack from the concession stand. This means that the total cost of the tickets would be 4 × 7 = $28

If Mr. Moore's mom paid $42 for the group's tickets and snacks, it means that total cost of tickets + total cost of snacks = $42

Let the cost of each snack be $x

Since they are 4 persons and total cos of snacks and tickets is $42,

Total cost of snack will be 4 × x =

Total cost of ticket will be 4 × 7. So

(4 × x) +(4 × 7) = 42

Factorising 4, the expression becomes

4(x + 7) = 42

Solving the equation,

4x + 28 = 42

4x = 42 - 28 = 14

x = 14/4 = 3.5

Each snack cost $3.5

The 4 snacks cist $14
