Question 79655
Let x=number of regular orders sold;  
$5.99x=receipts from regular orders
Then 134-x=number of jumbo orders sold; 
$8.99(134-x)=receipts from jumbo orders

Now we are told that :

5.99x+8.99(134-x)=1024.66    get rid of parens ($ are understood)

5.99x+104.66-8.99x=1024.66  subtract 1204.66 from each side

5.99x+1204.66-1204.66-8.99x=1024.66-1204.66 collect like terms

-3x=-180  divide both sides by -3

x=60---------------------------------number of regular orders sold

134-x=134-60=74--------------------------number of jumbo orders sold


CK

60*5.99+74*8.99=1024.66

359.40+665.26=1024.66
1024.66=1024.66


Hope this helps----ptaylor
