Question

You order two servings of pancakes and fruit cup. The cost of the fruit cup is $1.50. you leave a 15% tip. Your total bill is $11.50. How much does one serving of pancakes cost?

Answer 1

One serving of pancakes costs `$4.25`.

Explanation:

We can write our problem as an equation. Notice that 1.15 is 115% (entire cost + 15% tip) in decimal form.

`1.15(2x+1.50)=11.50`

From here, we can use the distributive property and solve for x:

`2.3x+1.725=11.50`
`2.3x=9.775`
`x=$4.25`
