Answer: A. 100%
Step-by-step explanation:
The number of kids in your group is 12.
Step-by-step explanation:
Given,
Number of people = 20
Cost of each kid ticket = $4
Cost of each adult ticket = $6
Total spent = $96
Let,
x be the number of kids ticket
y be the number of adult ticket
According to given statement;
x+y=20 Eqn 1
4x+6y=96 Eqn 2
Multiplying Eqn 1 by 4

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 2

Putting y=8 in Eqn 1

The number of kids in your group is 12.

1/2 + 9/20 = 19/20
1/20 + 1/10 = 3/20
1/8 + 11/16 = 13/16
2/9 + 5/9 = 7/9
3/20 + 3/4 = 18/20 = 9/10
7/17 + 1/17 = 8/17
Answer:
y < 1.1
Step-by-step explanation:
<u>Step 1: Subtract 2.1 from both sides
</u>
-4.2y + 2.1 - 2.1 > -2.52 - 2.1
<em>-4.2y > -4.62</em>
<em />
<u>Step 2: Divide both sides by -4.2</u>
-4.2y / -4.2 > -4.62 / -4.2
<u><em>Since you divided by a negative, that flips the sign.</em></u>
<em>y < 1.1
</em>
Answer: y < 1.1
