Cool treats sold 60 ice cream cones.Single dip cones sold for $2.50 each and double dip cones for $4.15 each.In all $179.70 was taken in for the cones.How many of each size cone were sold?.I was helped for most of it but am stuck at the multiplying part.

Best ResponseYou've already chosen the best response.0x = single dip y = double dip 60 = total ice creams x + y = 60 our second equation would be: $2.50x + $4.15y = $179.70 you can use the substitution or the elimination method to solve for either x or y.

Best ResponseYou've already chosen the best response.0Let's solve for x = single dip We will take the easy equation: x + y = 60 subtract x from both sides y = 60  x now your value for y (in the second equation) is y = 60 x Now place it into the second equation: $2.50x + $4.15(60  x) = $179.70 this is so much easier to do because now you have only one variable to solve for (x), instead of two ( x and y ). solve for x and we will move on to the next step.

Best ResponseYou've already chosen the best response.0The part where I am subtracting the 60 from x?

Best ResponseYou've already chosen the best response.0We want to solve for x, and that will lead us to finding the amount of single dip cones. The reason for why we are isolating y is to get the value of it. Instead of having two variables in front of us, we will have one (and that is x  the variable that we are solving for).

Best ResponseYou've already chosen the best response.0Therefore, we can plug in y = 60  x into the second equation where y is (next to $4.15). if you look at that then you can see that there is only x.
