Golf balls cost $0.90 each at Jerzy’s Club, which has an annual $25 membership fee. At Rick and Tom’s sporting-goods store, the
1 answer:
Answer:
See attached graph.
Step-by-step explanation:
Each situation can be expressed as an equation:
<u>Jerzy: </u> Total Cost (y1) is the $25 membership fee plus $0.80/golf ball (x):
y1 = $25 + $0.90x
<u>Rick and Tom's:</u> Total Cost (y2) is $1.25 per golf ball, x.
y2 = $1.25x
See the attached graphs of these two equations. Jerzy's cost less after 56 balls are purchased.

Given:
Jada traveled 135 miles in 3 hours.
Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.
To find:
How far did Jada travel in 1 hour?
Solution:
We have,
Distance traveled by Jada in 3 hours = 135 miles
Then,
Distance traveled by Jada in 1 hour = miles
= 45 miles
Therefore, Jada travel 45 miles in 1 hour.

<h2>Hello!</h2>
The answer is:
To calculate the speed of the cars, we need to write two equations in order to create a relation between the two speeds and be able to isolate one in function of the other.
So, let be the first car speed "x" and the second car speed "y", writing the equations we have:
For the first car:
For the second car:
We know that the speed of the second car is the speed of the first car plus 14 mph, so:
Now, we already know that both cars met after 2 hours and 45 minutes, meaning that positions will be the same at that moment, and the distance between A and B is 264 miles, so, we can calculate the relative speed between them:
If the cars are moving towards each other the relative speed will be:
Then, since we know that they covered a combined distance which is equal to 264 miles of distance in 2 hours + 45 minutes, we have:
Writing the equation, we have:
We have that the speed of the first car is equal to 41 mph.
Now, for the second car we have that:
Hence, we have that:
Have a nice day!
