someone counted how many stuffed animals each student has. stuffed animals how many students are there in all? students

Explanation:

Step1: Count the number of Xs in each column

• For \(0\) stuffed animals: \(7\) Xs
• For \(1\) stuffed animal: \(10\) Xs
• For \(2\) stuffed animals: \(8\) Xs
• For \(3\) stuffed animals: \(5\) Xs
• For \(4\) stuffed animals: \(2\) Xs
• For \(5\) stuffed animals: \(3\) Xs
• For \(6\) stuffed animals: \(8\) Xs

Step2: Sum up all the counts

$$7 + 10+8 + 5+2 + 3+8$$

$$=(7 + 10)+8 + 5+2 + 3+8$$

$$=17+8 + 5+2 + 3+8$$

$$=(17 + 8)+5 + 2+3 + 8$$

$$=25+5 + 2+3 + 8$$

$$=(25 + 5)+2 + 3+8$$

$$=30+2 + 3+8$$

$$=(30 + 2)+3 + 8$$

$$=32+3 + 8$$

$$=(32 + 3)+8$$

$$=35+8$$

$$=43$$

Answer:

\(43\)
