Answer:
The decrease in percent is 50 %
Step-by-step explanation:
Initial point is 90 while the final point is 45. We need to find the percent decrease. Percent change is given by :
[tex]\% =\dfrac{\text{change}}{\text{original amount}}\times 100[/tex]
[tex]\% =\dfrac{90-45}{90}\times 100[/tex]
[tex]\%=50\%[/tex]
So, the percent decrease is 50 percent. Hence, this is the required solution.
