Answer:
Mary = 34, George = 16, Carrie = 8, Jennifer = 10
Step-by-step explanation:
Set up the system of equations from the given information.
1) m = g + 18
2) g = 2 * c
3) c = j - 2
4) j = 10
Solve each equation one by one:
Plug eq.4 into eq.3:
5) c = 10 - 2 = 8
Plug eq.5 into eq.2:
6) g = 2 * 8 = 16
Plug eq.6 into eq.1:
m = 16 + 18 = 34
Domain is 0 to 50.
in the survey, 16 out of 80 students who where asked favored chicken nuggets.
so we need to calculate like this:
530 * 16/80
=530 * 1/5
=530/5
=106
hope this helps your understanding, wish you good grades
