00:00 - 00:59 | question station cells regular gasoline for 2.3 $9 per gallon and premium gasoline hot 2.79 Dollars per gallon station sold a total of 550 gallons of both types of gasoline in one day for a total of 1340 4.5 dollars how many gallons of premium gasoline was firstly ladiss ke number of gallons regular gasoline |

01:00 - 01:59 | short equal to X in one day and number of Galaxy of premium gasoline sold in one day and is also in one this is equal to what we can write our question as a system of linear equations in two variables pair of linear equations in two variables so we know that the total amount of Gal old is equal to 550 plus Wi-Fi setting amount of money made is 1344.5 |

02:00 - 02:59 | 2.39 into a price of normal gasoline plus 2.79 into why price of premium gasoline equal to 13 4.5 we have this number what we can do is we can write from the first equation we can take X equal to 50 - 1 and put this value in this equation and get the answer of what is Y equal to what we need to find this question can find the value of Y and select the answer so put this into this we get 2.39 into 550 minus Y + |

03:00 - 03:59 | 2.79 of Y equal to 13 4.5 so when we do this multiplication we get 13 14.5 - 2.39 Y + 2.79 Y2 134.5 new now we will take this constant term on this site and subtract these two terms of why so we get point 40 Y equal to 13 44.5 -13 14.5 this equals to 30 |

04:00 - 04:59 | this calculation under 2.3 Nain 2550 you can do it on calculator Indian dancer and this one just do it manually because it 13 1340 4.5 -1314.5 that many as 30 and get Y is equal to 30 / 0.40 so this we can either on calculator for Speed mananiy we will get 300 which is nothing but 7575 gallons of premium gasoline was sold for Y is equal to 75 show |

05:00 - 05:59 | the answer choices which use is B |
