Answer:
3x + 1y = $163
2x + 3y =$174
Step-by-step explanation:
Adult tickets to space amusement park cost x dollars children’s tickets cost y dollars.
Henson family bought 3 adults and 1 child's tickets for $163
x + y = 163
3x + 1y = 163
The Garcia family bought 2 adults and 3 child’s ticket for $174.
x + y = $174
2x + 3y = $174
Therefore the equations representing both families cost are
Henson family
3x + 1y = $163
Garcia family
2x + 3y = $174

Answer:
Mark up = 33.33%
Step-by-step explanation:
Given that:
buying price = $75
selling price = $100
First we will find the difference between two prices:
Difference = 100 - 75 = $25
We will find now that 25 is what percent of 75 so:
=25/75* 100
= 0.333333 * 100
= 33.33%
So the store marked the price by 33.33% instead of 30%

Answer: $1.5
Step-by-step explanation:
$3.00 divided by 2 pounds is $1.5
$4.50 divided by 3 pounds is $1.5
and $6.00 divided by 4 pounds $1.5
Step 1: Subtract 28x from both sides.
4x2−28x=28x−28x4x2−28x=0
Step 2: Factor left side of equation.
4x(x−7)=0
Step 3: Set factors equal to 0.
4x=0 or x−7=0
Answer:x=0 or x=7
