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 WILL GIVE MEDAL FOR CORRECT ANSWER!!!!

OpenStudy (mathstudent55):

1 shirt + coupon = 1 * $11 - $6 = $11 - $6 = $5 2 shirts + coupon = 2 * $11 - $6 = $22 - $6 = $16 3shirts + coupon = 3* $11 - $6 = $33 - $6 = $27 This is it.

OpenStudy (anonymous):

Well, 27-6=21 which is not equal to 22, therefore you can only buy one t-shirt. @MathStudent You only have one coupon which means it is incorrect.

OpenStudy (anonymous):

so the answer is 3

OpenStudy (anonymous):

Nope, it's actually one since you have 1 coupon, not 3.

OpenStudy (anonymous):

You could actually buy 3 shirts even though you have 1 coupon. $11.00-$6.00=$5.00 $11.00+$5.00=$16.00 $16.00+$11.00=$27.00

@drewsorr1 Where did you get $27 from for your subtraction of $27 - $6 = $21?

OpenStudy (anonymous):

$27 = Money gathered to spend at the Mall.

OpenStudy (mathstudent55):

Good. Why did you subtract $6 from it to get 27 - 6 = 21? What does a coupon for $6 off mean?
