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)
The total cost of the Granny Smith apples is $1.35 x 6 = $<<1.35*6=8.10>>8.10.
So, Dahlia spent $15 - $8.10 = $<<15-8.10=6.90>>6.90 for the Macintosh apples.
Therefore, the cost of each Macintosh apple is $6.90/6 = $<<6.90/6=1.15>>1.15. Answer: \boxed{1.15}.
