After Valerie is seated in the restaurant she realizes she only has $20.00. If she must pay 7% sales tax and wishes to leave a 15% tip on the total bill.

Question

what is the maximum price of the lunch she can order

Answer 1

X = maximum price Valerie can order.

 

X + 7% tax + 15% tip = $20

 

X+ 0.07 * X + 0.15 * X = 20

 

(1 + 0.07 + 0.15) X = 20

1.22 * X = 20

Can you solve the rest?
