Dahlia bought Granny Smith and Macintosh apples at the grocery store. The Granny Smith apples were $1.35 each if you bought 6. Find the cost of each Macintosh apple if the total cost is $15 and she bought 6 of each. (1 point)
There are a total of 6 + 6 = <<6+6=12>>12 apples.
She spent 6 * $1.35 = $<<6*1.35=8.1>>8.1 on Granny Smith apples.
She spent $15 - $8.1 = $<<15-8.1=6.9>>6.9 on Macintosh apples.
The Macintosh apples are $6.9 / 6 = $<<6.9/6=1.15>>1.15 each. Answer: \boxed{1.15}.
