Answer:
$29.67
Step-by-step explanation:
first you would fin out how much the total would be with the sales tax( which is equal to $4.89) added to the initial cost which should add up to $77.39
the 15% tip would add $11.61 to the $77.39
divide 89 by 3 which should give you 29.67
She starts out with 3 dollars, and then she found 75 cents. 5 quarters are equal to $1.25.
The equation would be: (3 + 0.75) - 1.25
There are 11 full tables, because when you divide 138 by 12 you get 11 remainder 6. So there is 11, because 12 people are at 11 tables and 6 at one!
