Now for the Money Part!

• Mario has 150 now
• He needs to spend 35 on gloves and various
  supplies
• He must pay 2.20 gas money for each day he
  works

The Critical Question

• How much should Mario ask to be paid per hour?
• He wants to make just enough to buy the PS3 on
  Dec 1st.
• He also needs to have at least 575 to ensure all
  costs are covered.

Hint

• Marios current money,
• Plus the hours he works times how much he gets
  per hour
• Minus 2.20 times his days worked
• Minus 35 for supplies
• Should be equal to or greater than 575

10
Hint Written as an Inequality

• Let X equal the amount paid per hour
• 150 11(3) 2(8)X 2.20(13) 35 575
• 150 33 16X 2.20(13) 35 575
• 150 49X 2.20(13) 35 575
• 150 49X 28.6 35 575
• 150 28.6 35 49X 575
• 86.4 49X 575
• 49X 575 86.4
• 49X 488.6
