Answer :

[tex]\begin{gathered} A)7.50x=187.5 \\ \text{part b)} \\ B)25 \end{gathered}[/tex]

Explanation

Step 1

Aya sold printed T-shirts for $7.50 each at a carnival. She earned

$187.50.

then

let x represents the number of T-shirts Aya sold.so, if she made $187.5 and the cost per T-shirt is $7.50

[tex]\begin{gathered} \text{total}=\text{ rate}\cdot\nu mber\text{ of T-shirt} \\ \text{replace} \\ 187.5=7.5x \\ or \\ 7.50x=187.50 \end{gathered}[/tex]

therefore, for part A , the answer is

[tex]A)7.50x=187.5[/tex]

Step 2

What is the number of T-shirts Aya sold at the carnival?

to figure out this,we need to solve for x

[tex]\begin{gathered} 7.5x=187.5 \\ \text{divide both sides by 7.5} \\ \frac{7.5x}{7.5}=\frac{187.5}{7.5} \\ x=25 \end{gathered}[/tex]

it means she sold 25 T-shirts at the carnival

I hope this helps you
