A cafe offers senior citizens a 15% discount off its regular price of $8.95 for the dinner buffet.
jonny [76]

a) 75 percent of the regular price is the price for senior citizens.

b) $6.712 is the price for senior citizens.

<u>Step-by-step explanation</u>:

  • The regular price is the 100% = $8.95
  • The offer price for senior citizen = 15% discount from 100%

∴ Percent of the regular price for senior citizens = 100% - 15% = 75%

The price for the senior citizens = 75% of $8.95

⇒ (75/100)\times8.95

⇒ 0.75\times8.95

⇒ 6.712 dollars.

∴ The price for senior citizens = $6.712
