Jenny went to the sale at Kohl's last weekend.  
T-shirts were on sale for $15 each and hoodies were on sale for $20 each.  If she spent $150 total, write an equation to represent this situation.  

• 20x + 15 = y 
• 35x = y 
• 15x + 20y = 150 
• 150 - 20x = 15y 

How can I tell if an inequality will have a solid line?

• It has an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.

What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

A sporting goods store sells left handed (x) and right handed (y) gloves. In one month, 12 gloves were sold for a total of $561. Right handed gloves cost $45 each and left handed gloves cost $52. Which system could be solved to determine the number of each type of glove sold?

• x + y = 561

  45x+52y=12

• x + y = 12

  52x+45y=561

• x + y = 12

  45x+52y=561

• x + y = 561

  52x+45y=12
