cost of each book is $3. He also wants to buy one poster for $2. Write an inequality to show how
many books he can buy. Highlight your inequality in green. Then,solve the inequality

Answer 1

7 books

Explanation:

i cant write it in an equaction but basically 25 - 2 = 23

then 3 x 7 = 21 so he can only buy 7 books and he'll have 2 dollars left

Answer 2

3x + 2 = 25. x= 7

3x +2 =25
-2 -2
23
3x = 23


23 divided by 3 = 7
