At a bakery Ada buys a cake for $20. She also buys four cookies. If she spent $28 total on the cake and cookies how much does each cookie cost

1 answer

To find the cost of each cookie, we can start by setting up an equation based on the information provided.

  1. Let the cost of each cookie be \( x \).
  2. Ada buys one cake for $20.
  3. She buys four cookies, so the total cost for the cookies is \( 4x \).
  4. The total amount spent on the cake and cookies is $28.

We can set up the following equation:

\[ 20 + 4x = 28 \]

Now, we can solve for \( x \):

  1. Subtract 20 from both sides:

\[ 4x = 28 - 20 \]

\[ 4x = 8 \]

  1. Divide both sides by 4:

\[ x = \frac{8}{4} \]

\[ x = 2 \]

Thus, each cookie costs $2.
