the singh and robinson families planned a trip to busch gardens. they needed to buy one ticket per person and then pay for parki
hjlf

Let x represent cost of each ticket and y represent cost of parking.

We have been given that the Singh's spent $335 for 5 people and parking. We can represent this information in an equation as:

5x+y=335...(1)

We are also told that the Robinson spent $465 for 7 people and parking. We can represent this information in an equation as:

7x+y=465...(2)

Now we will use elimination method to solve our given system of equations.

Upon subtracting equation (1) from equation (2), we will get:

7x-5x+y-y=465-335

2x=130

\frac{2x}{2}=\frac{130}{2}

x=65

Therefore, the each ticket costs $65.

Upon substituting x=65 in equation (1), we will get:

5(65)+y=335

325+y=335

325-325+y=335-325

y=10

Therefore, the parking costs $10.

Find the percent of change. 120lbs to 1801bs
mart [117]
Quick Note: I'm pretty sure you meant 180LBS and not 1801bs, so I'm using 180, but if it was 1801 please tell me

Percent of change = \frac{V2 - V1}{V1} *100

Substitute 180 for V2 and 160 for V1
Percent of change = \frac{180-160}{160} * 100

Solve
Percent of change = \frac{20}{160} *100
Percent of change = 0.125 x 100
Percent of change = 12.5%
