Those 16 problems cost him 34%
One problem is worth 34/16 = 2.0625
So each question is worth about 2 point.
2*x = 66 Divide by 2
x = 66 /2 = 33 questions that he got right.
The total number of questions is 33 + 16 = 49
Does the rounding really matter?
2.0625 x = 66
x = 66/2.0625
x = 32 yes it matters.
Total number of questions = 32 + 16 = 48 <<<< answer.
The were 35 child tickets sold and 3 adult tickets sold.
How did I get this?
First, let's look at what we know.
Matinee
(C)hild ticket = $1
(A)cult ticket = $2
Regular
(C)hild ticket = $4
(A)cult ticket = $6
2. We need to make two equations out of this:
1C + 2A = $41
4C + 6A = $158
The variables represent the amount of tickets, which is the unknown.
3. Process of elimination, multiply the first equation by -3 because we want to cancel out one set of variables.
-3(1C + 2A = 41)
-3C - 6A = -123
4C + 6A = 158
C = 35 child tickets
Substitute the value c into any one of the equations
1(35) + 2(A) = $41
$35 + 2A = $41
Subtract both sides by $35.
2A = $6
Divide by 2
A = 3 adult tickets
Answer:
5 x
Step-by-step explanation:
if its scientific notation
46/69 * 100
0.66666*100
which is 66percent
