You have $27.00 to spend at the mall and a coupon for $6.00 off at your favorite store. A t-shirt costs $11.00. How many t-shirts can you buy using your coupon and money?

Answer 1

With the coupon, the total amount we need to subtract from our $27.00 is $6.00.
$27.00 - $6.00 = $<<27-6=21.00>>21.00
Each t-shirt costs $11.00.
So, $21.00 / $11.00 = <<21/11=1.9090909090909092>>1.91 t-shirts.
Since you cannot buy a fraction of a t-shirt, you can buy 1 t-shirt. Answer: \boxed{1}.
