<PRE><B>Question 1126421</B>
&lt;br&gt;
The algebraic solution method shown by the other tutor is fine.&lt;br&gt;
Here is a method for finding the solution with less work than the formal algebra, using logical reasoning and a bit of mental arithmetic.&lt;br&gt;
If all 200 cones were single scoops, the total sales would be $200; but it is $21.75 more than that.&lt;br&gt;
The difference between the price of a single scoop and a double scoop is $0.25; the number of double scoop cones required to make that additional $21.75 is&lt;br&gt;
{{{21.75/.25 = 87}}}&lt;br&gt;
So....&lt;br&gt;
ANSWERS:&lt;br&gt;
There were 87 double scoop cones sold and 200-87 = 113 single scoop cones.&lt;br&gt;
The total number of scoops sold was 200+87 = 287.</PRE>
