C = children
A = adults
293 = c + a
1.50c + 2.50a = 676.50
We can use substitution to solve:
c + a = 293 subtract a to get c = 293 - a
Plug this into the second equation:
1.50(293 - a) + 2.50a = 676.50
439.5 - 1.50a + 2.50a = 676.50
439.5 + 1a = 676.50
a = 237
Substitute this into the first equation:
293 = c + 237
56 = c
Answer:
so first convert to fraction so
9 3/4 = 39/4
so it was spread among 3
so this is division so you do 39/4 divided by 3
so you keep switch flip
which is 39/4 *1/3
answer is 13/4
Answer:
B
Step-by-step explanation:
When you double the dimensions of a triangle, the area is four times as large, so if you quadruple it, it would be 16 times as large
Answer:

Step-by-step explanation:
Answer:4
Step-by-step explanation:
Ex (increase, such as taxes or price hike):
I want to increase $5 by 20%.
That means I would have to find the product of $5 and 120%.
$5*1.20=6
If you increase $5 by 20%, you will get $6.
Ex (decrease, such as a discount or a special deal):
I want to decrease $5 by 20%.
That means I would have to find the product of $5 and 80%.
$5*.80=4
If you decrease $5 by 20%, you will get 4.
