You purchased equipment costing $1,000 to use for a lawn-mowing business to earn money for college during the summer. the first week in july, your college roommate asks you to him paint a house the following week. if you agree, you will have no time to mow. revenue from mowing would be $1,200. your roommate has offered you $1,400 to him paint. additional mowing costs for the week would be $100, and additional painting costs would be $80. transportation costs would be $50 for either job. what is your incremental net income for the week if you choose to paint?

$220

Explanation:

For Mowing:

Revenue:                                      $1,200

Additional cost:                              $(100)

Transportation cost :                      $(50)

Net Income               :                  $1050

For Painting:

Revenue:                                      $1,400

Additional cost:                              $(80)

Transportation cost :                      $(50)

Net Income               :                  $1270

Incremental Net income =   $1270 -  $1050

                                            = $220

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
