High School

Brandon and his friends are preparing for an epic snowball fight. They make 75 snowballs before Brandon's dad calls them in for lunch. After lunch, they make more snowballs. In all, Brandon and his friends make 157 snowballs.

Which equation can you use to find the number of snowballs [tex]s[/tex] Brandon and his friends make after lunch?

A. [tex]75 + s = 157[/tex]
B. [tex]\frac{s}{75} = 157[/tex]
C. [tex]s - 75 = 157[/tex]
D. [tex]s + 75 = 157[/tex]

Solve this equation for [tex]s[/tex] to find the number of snowballs Brandon and his friends make after lunch.

[tex]\square[/tex] snowballs

Answer :

To solve the problem about how many snowballs Brandon and his friends made after lunch, we need to find an equation that helps us calculate this number.

We start with the following information:

1. Before lunch, they made 75 snowballs.
2. After lunch, the total number of snowballs they made is 157.

Let's determine the equation that represents this situation. We want to find the number of snowballs, [tex]\( s \)[/tex], they made after lunch.

The correct equation that links these quantities is:

[tex]\[ s + 75 = 157 \][/tex]

This equation makes sense because it describes the total number of snowballs made in two parts: the 75 snowballs made before lunch plus the snowballs made after lunch which we are calling [tex]\( s \)[/tex].

Next, we solve this equation to find [tex]\( s \)[/tex]:

1. Start with the equation:
[tex]\[ s + 75 = 157 \][/tex]

2. We need to isolate [tex]\( s \)[/tex] by subtracting 75 from both sides of the equation:
[tex]\[ s = 157 - 75 \][/tex]

3. Calculate the right side:
[tex]\[ s = 82 \][/tex]

So, Brandon and his friends made 82 snowballs after lunch.
