Question

How do I set up the equation for “you order 3 servings of pancakes and a fruit cup. The cost of the fruit cup is 1.50. W a 15% tip equal 11.50. How much is one pancake

Answer 1

If you add 15%, you have 115% of the price before tax.

 

1.15(p + 1.50) = 11.50

(1.15(p + 1.50))/1.115 = 11.50/1.15

p + 1.50 = 10

p + 1.50 - 1.50 = 10 - 1.50

p = $8.50
