Linear Equations Word Problems #1

An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute.  Write an equation to model the situation.

• y = 30,000ft - 2,000ft(x)
• y = 30,000ft + 2,000ft(x)
• y = 30,000ft(x) - 2,000ft

 At a school play, children’s tickets cost $3 each and adult tickets cost $7 each. The total amount of money earned from ticket sales equals $210. Write a linear model that relates the number of children’s tickets sold to the number of adult tickets sold. Let x = the number of children’s tickets sold and y = the number of adult tickets sold

• y=10x+210
• 7x+3y=210
• y=7x+210
