Answer:
Cost of each salad = $12
Explanation:
Olivia ate at the same restaurant four times. she ordered a salad and left a $1.50 tip on each visit. She spent a total amount of $54.
Let x be the cost of salad
She ate the salad four times. So the cost of 4 salad is 4x
Then she left a tip of 1.50 each visit. 4 times 1.50 = 6 dollars
Total cost is $54
cost of 4 salads + tip amount is equal to total cost
![4x+6= 54](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jfcgwscgj9axtqlazt5vmj86rv98jci40i.png)
Solve for x
Subtract 6 from both sides
![4x= 48](https://img.qammunity.org/2020/formulas/mathematics/middle-school/v5rrf1pzooenevkyc7v8tt1v5h6cx4nw14.png)
Divide both sides by 4
x=12
Cost of each salad = $12
