Answers:

bio = 258

sociology = 169

============================================================

Work Shown:

x = number of bio textbooks

y = number of sociology textbooks

x+y = 427 books sold total

y = x-89 since 89 less sociology textbooks were sold compared to bio

Apply substitution to get the following

x+y = 427

x+x-89 = 427 ... replace y with x-89

2x-89 = 427

2x = 427+89

2x = 516

x = 516/2

x = 258 bio textbooks were sold

y = x-89

y = 258-89

y = 169 sociology textbooks were sold

zmey [24]

Total monthly saving = $1,315

<h3>What are savings?</h3>

Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.

Given:

                        Oakland     Los Angeles  

Cost Housing       $565        $1200

Food                     $545        $655

Health Care         $245        $495

Taxes                    $450         $625

Other Necessities $350        $495

Now,

Saving in house

= $1200 - $565

= $635

Saving in food

= $655 - $545

= $110

Saving in health care

= $495 - $245

= $250

Saving in taxes

= $625 - $450

= $175

Saving in necessities

= $495 - $350

= $145

Total saving = $635+$110+$250+$175+$145

                    = $1,315

Hence, the monthly savings should be $1,315.
