Write an equation and solve to find the solution to the following problem.

You have $27 to spend at the mall and a coupon for $6 off at your favorite store. A t-shirt costs $11. How many t-shirts can you buy using your coupon and money?

1 shirt
2 shirts
3 shirts
4 shirts

1 answer

Let x be the number of shirts you can buy. The cost of each shirt is $11, and you have a coupon for $6 off. So, the equation is given by:

11x - 6 = 27

Simplifying the equation:

11x = 33

Dividing both sides by 11:

x = 3

You can buy 3 shirts using your coupon and money.
