96.64% decrease
Explanation:
We should see that the price has decreased from it's original selling price.
decrease = 149 - 5 = $144
To express the decrease as a percentage decrease. Write the decrease (144) as a fraction of the original cost (149) and multiply by 100.
%decrease
#=144/149xx100/1=(144xx100)/149=96.64#
