Brianna works at a sunglass shop. She earns $9 per hour and a $1 commission for each sale she makes. From July 1 to July 5, she saves all her money and doesn’t spend anything.

Each day, from July 1 to July 5, Brianna worked 4 hours.

• On July 1, Brianna made 4 sales.

• On July 2, Brianna made 3 sales, and worked 1 extra hour.

• On July 5, Brianna made 2 sales.

If Brianna had $225 at the end of July 5, how much money did she have on the morning of July 1?
