Yen put $50 of gas in his truck. The price per gallon was $4. Write an equation that could be used to find the number of gallons
Allushta [10]
<em>g </em>= gallons.

50 ÷ 4 = g ; which this would then show us that if we were to divide 50 by 4, this would then give us a total of 12.5 which this would show us that would be the amount that he has putted in his truck.

So we need to compare them at the sam ounches


find the least common multiple (the smallest number that they will both multiply into)

first find the factors and group them all together, delete any repeats


6=2*3
8=2*2*2

least common multiple=2*2*2*3=24

so 6 bags=2.46
multiply by 4 to get 24
24 bags=9.84






so 8 bags=3.20
multply by 3
24 bags=9.60


9.84>9.60 so

the 8 ounce bag is less expensive
