2.39x+2.79y=1344.50 where x is regular and y is premium
x+y=550
U will get x=475 y=75
75 gallon premium
It’s should be letter b I hope you have a great day
Let x represents the numbers of hours that Billie and Toni are driving after first day and ‘Y’ represent the distance they have passed distance
Y=420+65
And, first day they traveled : 410 mi
2nd day they traveled =65.8=520 mi
3rd day they traveled =65.8=520
By the end of the third they traveled= 420+520=520
1460 mi
We can say that there are 20 blueberry muffins for every 15 bran muffins, according to the given information. This can be expressed as 20:15 in ratio form. We can simplify this ratio further, by dividing both sides by 5, to leave us with the simplified ratio of blueberry to bran muffins, 4:3
