A company charges $9 for a tshirt and ships any order for $10.  A school principal ordered a number of tshirts for the school store.  The total cost of the order was     $1, 480.  Write an equation that can be used to find the number of tshirts ordered.

• 9 + 10x = 1480
• 1480 - 10x = 9
• 9x + 10 = 1480
• 9x - 1480 = 10

Precious has $45.62 to spend on painting classes.  Each class costs $7 plus a one time registration fee of $6.25.  let the variable, n, represent the number of classes.  Which equation represents the number of classes Precious can attend for $45.62?

• 7 + 6.25x = 45.62
• 7x + 6.25 = 45.62
• 45.62 - 6.25x = 7
• 7 + 45.62 = 6.25x

What is the value of x in the equation below?
20x + 130 = 710

• 42
• 290
• 29
