Answer:
8
Step-by-step explanation:
We have, 25% × x = 200
or,
25
100
× x = 200
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 200 ×
100
25
x = 800
If you are using a calculator, simply enter 200×100÷25, which will give you the answer.
So now that you have the original number you just need to find 1% of 800
1% of 800 is 8
Answer:
true
Step-by-step explanation:
Answer:
let
c = the number of covered pavilion tickets sold
l = the number of lawn seats tickets sold
one evening 1400 concert tickets were sold
c + l = 1,400
total receipts were $30,000
30c + 15l = 30,000
by solving the system of equations
c + l = 1,400
30c + 15l = 30,000
we find
c = 400 covered pavilion seats
l = 1,200 lawn seats
by plugging the correct numbers into each other
