Answer:
Price for Senior Citizen = $7.61
Percent of the regular price = 85% off original
Step-by-step explanation:
Regular Price is $8.95
Seniors get 15% off of that. So, first we need to find 15% of 8.95 and then subtract it from 8.95.
To get percentage of a number, we first convert the percentage to decimal (by dividing by 100) and then multiply it with the number.
15% = 15/100 = 0.15
Fifteen Percent of 8.95 is:
0.15 * 8.95 = $1.3425
Senior Citizen Price = 8.95 - 1.3425 = $7.6075
Rounded to nearest cent = $7.61
How much is this as a percentage of original?
Simple, it is 15% off of the regular price, so this price is 100 - 15 = 85% of original price
