Question

how many bones does colby pack after lunch?
colby packs ______ bones after lunch.

the camp has some tents.
campers set up 42 more tents.
now the camp has 60 tents.
how many tents did the camp have to begin with?

the camp began with ______ tents.

Explanation:

Step1: Define the unknown

Let the number of tents the camp began with be $x$.

Step2: Set up the equation

The camp started with $x$ tents, then set up 42 more tents, and now has 60 tents. So the equation is $x + 42 = 60$.

Step3: Solve for $x$

To find $x$, we subtract 42 from both sides of the equation: $x = 60 - 42$.

Step4: Calculate the result

$60 - 42 = 18$.

Answer:

The camp began with 18 tents.
