Answer:
-3
Step-by-step explanation:
So it's 2.40 subtract 2, which is 0.4
then put it over 2, you get 0.4/2, which is equal to 0.2
0.2= 20% so it's 20% of increase
Answer:
True
Step-by-step explanation:
X - number of the adults, y - number of children;
The system is:
10 x + 6 y = 3292
x + y = 350 => y = 350 - x
----------------------
10 x + 6 * ( 350 - x ) = 3292
10 x + 2100 - 6 x = 3292
4 x = 3292 - 2100
4 x = 1192
x = 1192 : 4
x = 298
y = 350 - 298
y = 52
Answer:
There were 598 adults and 52 children at the showing.
