Step-by-step explanation:
let the restaurant bill be 100%

(8×100) ÷50
Ans 16%
the cosine is a cyclical function, so it cycles through from 0 all the way to the left and from 0 all the way to the right, nonstop, so its domain is (-∞, +∞), namely all real numbers.
Your total is $207 that was in the account before he added the $27.
Ava's sister paid a 4.5% annual interest rate
Her sister paid $54 more than she borrowed, divide that by 3 (years till she paid)
54/3 = 18
That's $18 for every year she'd had the $400 loan out, divide it by 4 to get the percentage
18/4 = 4.5/100 = 4.5%
