write an equation for the following sentence: Isabel sold t-shirts at a festival and made a profit of $71. She made $4 for each t-shirt she sold. Her total expenses were $25. How many t-shirts did she sell?

Answer 1

Let "x" represent the number of t-shirts Isabel sold.

The profit she made from selling the t-shirts can be calculated by multiplying the number of t-shirts sold (x) by the profit per t-shirt ($4): Profit = 4x.

The total amount of money Isabel made after selling the t-shirts can be represented as profit minus expenses: Total Income = Profit - Expenses.

According to the given information, the total income was $71 and the expenses were $25. Therefore, the equation can be written as:
Profit - Expenses = 71 - 25

Substituting the values:
4x - 25 = 71

So, the equation representing the situation is:
4x - 25 = 71.
