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)
Each Macintosh apple cost___ $
.
Let x be the cost of each Macintosh apple.
The total cost of the Macintosh apples is 6x dollars.
The cost of each Granny Smith apple is 1.35 dollars.
The total cost of the Granny Smith apples is 6 * 1.35 = <<6*1.35=8.1>>8.1 dollars.
The total cost of all the apples is x*6 + 8.1 = <<x*6+8.1=15>>15 dollars.
Combining like terms, we get x*6 = 15 - 8.1 = <<15-8.1=6.9>>6.9 dollars.
Dividing both sides by 6, we get x = 6.9/6 = <<6.9/6=1.15>>1.15 dollars.
Each Macintosh apple costs $1.15. Answer: \boxed{1.15}.
are you sure
I apologize for the mistake in my previous response. Let me correct it:
Let x be the cost of each Macintosh apple.
The total cost of the Macintosh apples is 6x dollars.
The cost of each Granny Smith apple is $1.35.
The total cost of the Granny Smith apples is 6 * $1.35 = $<<6*1.35=8.10>>8.10.
The total cost of all the apples is $15.
Therefore, we have the equation 6x + $8.10 = $15.
Subtracting $8.10 from both sides, we get 6x = $6.90.
Dividing both sides by 6, we find that x = $1.15.
Therefore, each Macintosh apple costs $1.15.
