The number of waffles there were initially is; 80 waffles
<h3>Simultaneous equations</h3>
Let the number of pancakes be x.
Let the number of waffles be y
Hence, after she baked 45 more waffles, and her grandchildren eat 12 pancakes, what she has is;
- y +45 waffles and x-12 pancakes.
There were 17 more waffles than pancakes.
- y+45 = x-12 +17.......equation (1)
And initially, x = 1.5y
Hence, to determine y, we must substitute x = 1.5y into equation (1)
Therefore, we have;
