Answer:
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.
