Olivia ate at the same restaurant four times. each visit she ordered a salad and left a $1.50 tip. she spent a total of $54. find the cost c of each salad

$12

Step-by-step explanation:

The cost of each salad is c

She visited the restaurant four times.

So, the total cost of salad should be 4c.

And each time she left a tip of $1.5

Therefore, total tip = 4 × 1.5 = $6

Now, it has been given that she spent a total of $54.

Therefore, we have

total cost of salad + amount spent on tip = 54

4c + 6 = 54

4c = 54-6

4c = 48

c = 12

Therefore, cost of each salad was $12.

the square root of what number? if you add that, then someone will probably answer the question.
