x = 3
Answer:
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5
Step-by-step explanation:
Let
x = number of people who order chicken dinner
y = number of people who order the steak dinner
x + y = 6 (1)
14x + 17y = 99 (2)
From (1)
x = 6 - y
Substitute into (2)
14x + 17y = 99 (2)
14(6 - y) + 17y = 99
84 - 14y + 17y = 99
- 14y + 17y = 99 - 84
3y = 15
y = 15/3
y = 5
Substitute y = 5 into (1)
x + y = 6 (1)
x + 5 = 6
x = 6 - 5
x = 1
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5

Answer:
12.36%
Step-by-step explanation:
For year 1:
T(1) = 1000(1.06)¹
T(1) = 1060
After two years, t = 3
T(3) = 1000(1.06)³
T(3) = 1191.06
The percent of the increase is
[(T(3) - T(2)/T(2)]*100%
[(1191.06 - 1060)/1060]*100%
12.36%
