A New Income Q&A

Q: Some word problem help here?

Ok here are the problems I need help with 1)A revenue of $1500 is obtained from the sales of item A at $50 each and item B at $25 each. Write an equation that shows the relationship between the numbers of items sold. 2)An airplane trip is traveling away from its home airport at a constant speed. After 3 hours, it is 540 miles away Assuming it departed at t=0, write an equation representing the distance, "D" (in miles), at any time "t" (in hours). 3)A real estate sales agent receives a salary of $250 per week plus a commission of 2% sales. Write a linear model for the weekly income "y" in terms of sales "x". 4)Machinery is bought new for $36,000 and is considered worth $2,000 as junk at the end of 10 years. Assuming a linear model for depreciation, write the equation of its value, "V" (in dollars), when "t" years have elapsed after the purchase. Please label your answers with a number to represent the question you are answering. Please explain the answer too.

A: 1. 50A + 25B = 1500, where A is the number of items type A sold, and B is the number of items type B sold. 2. d=distance, t=time, s=speed d=st (distance equals rate (speed) times time) 3. y = 250 + 0.02x, where x is the dollar value of sales made and y is total income 4. V = 36 - 3.4t, where V is the value in thousands of dollars.
