Delia bought Granny Smith and macadena Tosh apples at the grocery store The Granny Smith apples were each a dollar 35 each if you bought six find the cost of the Macintosh apples if the total cost is $15 and she bought six of each
If Granny Smith apples were bought at $1.35 each and Delia bought six of them, the total cost of Granny Smith apples would be 1.35 * 6 = $<<1.35*6=8.1>>8.1.
Let the cost of Macintosh apples be x dollars.
Delia bought six Macintosh apples, so the total cost of Macintosh apples would be 6 * x = 6x dollars.
The total cost of both types of apples is $15, so 6x + 8.1 = 15.
Subtracting 8.1 from both sides of the equation gives 6x = 15 - 8.1 = 6.9.
Therefore, the cost of the Macintosh apples is x = 6.9 / 6 = $<<6.9/6=1.15>>1.15. Answer: \boxed{1.15}.
