<u>Answer</u>:

40 cotton bags  and  120 peanuts bags

Step-by-step explanation:

Let cotton candy bags be x and peanuts bag be y

x + y = 160 ........from Theory 1

4x + 2.5y = $460 ...............from Theory 2

<u>Making x the subject:</u>

x + y = 160

x = 160 - y ...........equation 1

4x + 2.5y = $460

4x = $460 -  2.5y

x = ($460 -  2.5y)/4 ..............equation 2

<u>Solving both equations simultaneously:</u>

160 - y = ($460 -  2.5y)/4

4(160 - y) = $460 -  2.5y

640 - 460 = -  2.5y + 4y

180 = 1.5y

y = 180/1.5

y = 120

<em>Therefore there are 120 peanuts bags</em>.

Then the number of cotton bags are: x + y = 160

                                                            : x + 120 = 160

                                                            : x = 40 cotton bags
