Answer:

45−s=21   s=24

Step-by-step explanation:

The truck started with a total of 45 ice cream sandwiches. They sold an unknown number of sandwiches at the park, which we're calling s. The truck had 21, ice cream sandwiches remaining after the stop at the park.

Hint 2 / 5

We can represent the number of ice cream sandwiches the truck has remaining as a difference:

45-s   we know the has 21 ice cream sandwiches remaining.

Hint 3 / 5

We can set these two expressions equal to describe this situation with an equation:

45-s=21

Other ways to represent the situation with an equation include:  

45 - 21 = s

Hint 4 / 5

Now we can solve for s

Add s to both sides of the equation then subtract 21 from both sides:

45-s+s=21+s

     45=21+s

  45-21=21-21+s

         24=s

​

Hint 5 / 5

The following equation matches this situation:

45−s=21

The ice cream truck sold 24 ice cream sandwiches at the park
