Question

Write and solve an equation to answer the question. You order two servings of pancakes and a fruit cup. The cost of the fruit cup is $1.50. You leave a 15% tip. Your total bill is $11.50. What is the cost p of one serving of pancakes?

Answer 1

1.15(2x+1.50)=11.50
Divide both sides by 1.15 to isolate the parentheses:
2x+1.50=10
Subtract 1.50 from both sides:
2x=8.50
Divide by two on both sides :
X=4.25
It costs $4.25 for a serving of pancakes.
