Answer: 3
Step-by-step explanation:
Let’s write it out as an equation:
15s + 5 = 50
where s is the number of shirts she will buy.
Simplifying this equation, you get:
15s = 50 - 5 (since you move 5 to this right side)
15s = 45
[tex]\frac{15s}{15}[/tex]= [tex]\frac{45}{15}[/tex]
s = 3
Therefore, Sara can buy 3 shirts
