Carlos ate at the same restaurant four times. each time he ordered a salad and left 5$ tip. she spent a total of $54 right and solve an equation to find the cost of each salad.

4k + 20 = 54 is the required equation. ( k = cost of each salad)

The cost of each salad is $8.5.

Step-by-step explanation:

The total amount paid for bill = $54

The tip left each time $5

Number of times the restaurant visited = 4

Now, let k be the total amount of one salad.

Also, total tip paid in 4 visits =  4 x $5 = 20$

So, now according to the question

4k + $20 = $54

or, 4k = 54 - 20 = 34

⇒ 4k = 34

or, k = 34/4 = 8.5

⇒ k= $8.5

So, the cost of each salad is $8.5.
