Let the initial price be 100. Price after 1 month is 101.9. common ratio is r = 101.9/100 = 1.019
After 12 months, the price will be:
A1 x r ^n-1
= 101.9 * (1.019)^12-1
= 101.9 * 1.019^11= 125.34
So the yearly increase would be: 125.34 – 100 = 25.34
Therefore, the yearly price rise percentage is 25.34/100 x 100 = 25.34%

Answer:
93
Step-by-step explanation:
Let's set this up with a system of equations.
Represent hamburgers with h, and cheeseburgers with c.
The shop sold 279 total, so our first equation is h+c=279.
The cheeseburgers were 2x the hamburgers, so c=2h.
Now we have our system.
h+c=279
c=2h
Use substitution to solve.
h+c=279
h+2h=279
3h=279
h= 93
93 hamburgers were sold on Monday.
