Question 399731: I don't understand how to make a word problem into a linear system. This is an example in my Algebra I book:
You are planning a party for a friend. You can have the party at a pizza place for $8 per person plus $30 for favors and a small cake, or at a taco place for $12 dollars per person plus $14 for a large cake.
Could you please create a linear system from this data?

Question 399868: My teacher is a bad math teacher so I don't get this.
Question: Traveling upstream on the Missouri River, a barge travels 35 mi in 7 h. Downstream, it travels the same distance in half the time. What is the rate of the barge in still water and the rate of the current.
Please use the variable r[rate of barge in still water] and c[rate of current]
Could you please do the 4 steps process. If you do not know what the four step process is..it's 1st: let statement 2nd: equation 3rd: solve 4th: Writing the answer in a complete sentence. Thank you

Question 399882: A duck can fly 1800 m in 10 min with the wind. Against the wind, it can fly only 2/3 of this distance in 10 min. How fast can the duck fly in still air? What is the rate of the wind.
**PLEASE USE THE VARIABLES R for rate duck speed in still air and C for rate of wind. IF YOU DO NOT..I WILL GET CONFUSED SINCE I AM USING THOSE AND ONLY THOSE VARIABLES.

Question 399836: Hello! I'm stuck on this word problem and would appreciate if you could help me find 2 linear equations to help solve the following word problem:
The SBC yellow pages identifies two different local electrical businesses; Jones' charges $50 for a service call, plus an additional $39 per hour for labor, and Phenso charges $32 for a service call, plus an additional $45 per hour for labor. Write a system of equations and find the length of service where both companies would charge the same amount. I your electrical problem would take 4 hours to complete who would be the best choice to use?
I've tried but my confusion only grew worse. I ask to please help me solve this and how. :/
