The yogurt shop wants to mix two toppings together to create a new topping that will sell for $6 per pound. the caramel crunch costs $4 per pound, and pecan turtles cost $9 dollars per pound. how many pounds of each item must be mixed together to obtain 15 pounds of the new topping?

The answer is 5 lbs for each item
I hope this helped! If u need me 2 break it down plz comment so and I would b happy 2 do so!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
