Tina had no money until she received her pay from her boss. Afterward, she spent 7.50 dollars on food every day from Monday through friday. She spent 30 dollars on clothes and 25 dollars to repair her bike. If she had 40.50 left over what would be a expression to find the amount she received from her boss

(7.5 * 5) + 30 + 25 = x  40.5
