The answer is 106 your welcome :-)
\left[Y \right] = \left[ f(x)\right][Y]=[f(x)] .
I hope helping with u this answer
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
Multiply:
2 boxes x 5 packs each = 10 total packs
10 packs x 8 markers per pack = 80 total markers
Any: 80 markers
