Answer:
4.
Explanation:
Let x be the number of t-shirts that Maya can buy.
We have been given that Maya is taking her friends to a concert each ticket costs $25 and souvenir t-shirts are $12 each.
Since 1 t-shirt costs $12, so cost of x t-shirts wold be 12x.
We have been given that Maya bought 3 tickets, so amount spent on 3 tickets would be
.
We are also told that there is a $4 service fee for the entire purchase, so we can represent our given information in an inequality as:
![12x+75+3\leq 130](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lreswbcsef40viz9wv57sw6z9389nysm8k.png)
![12x+78\leq 130](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dft0gxzrfvz5vntlse7ntfv9xwvzk8wkjo.png)
![12x+78-78\leq 130-78](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zv5qeh3d9qoobtuv8rzpagywrky9ktcog2.png)
![12x\leq 52](https://img.qammunity.org/2020/formulas/mathematics/middle-school/54couwwgjxr5i79zzjf3lnqkdwjv6yizy2.png)
![(12x)/(12)\leq (52)/(12)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fh2l1apozmrdxgwu7kjhylf5mx6lm0nuc8.png)
![x\leq 4.33333](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ajb2mwc3kz8mbohgvpa6wh0qh3npwys5ms.png)
Therefore, the maximum number of t-shirts that Maya can buy is 4.
