Answer: 37.7
Step-by-step explanation:
10 % of 40 = 10/100 ×40=4
When dropped by 10% then amount on Monday = 40-4=36
On tuesday price dropped = 36 - 10 = 26
Increased by 45% on friday : 45/100 × 26 + 26 =
37.7
Percents are always whatever number over 100:
So for example, 35% is really 35/100:
35/100 as a number is .35
So when you get a percent and need to convert to a number, just divide by 100.
Hope this helps!
