At McDonalds, a chocolate chip cookie has 10 more calories than an ice cream cone. Together they have a total of 310 calories. How many calories does the chocolate chip cookie contain?

Let's solve the problem step by step:

1. Let the number of calories in the ice cream cone be \( x \).
2. Since the chocolate chip cookie has 10 more calories than the ice cream cone, the number of calories in the cookie is \( x + 10 \).
3. Together, the ice cream cone and the cookie have 310 calories, so we can write the equation:

\[
x + (x + 10) = 310
\]

4. Simplifying this equation:

\[
2x + 10 = 310
\]

5. Subtract 10 from both sides:

\[
2x = 300
\]

6. Divide both sides by 2:

\[
x = 150
\]

7. Since \( x = 150 \) represents the calories in the ice cream cone, the chocolate chip cookie has:

\[
x + 10 = 150 + 10 = 160
\]

Therefore, the chocolate chip cookie contains **160 calories**.
