Answer:
The price of the regular gasoline is $2.46, while the premium is $2.67.
Step-by-step explanation:
Let the price of regular gasoline be "x", while the price for the premium be "y", The sum of the amount of each type of gas multiplied by its cost should be equal to the total paid, therefore:

We also know that the premium gas costs 0.21 more than the regular one, therefore:

We can apply the second expression on the first, in order to solve for "x".


The price of the regular gasoline is $2.46, while the premium is $2.67.

Answer:
The answer is Dilation of a scale factor of 4 followed by a reflection of the y axis.
Step-by-step explanation:
On the smaller triangle, the line EF has a length of 1 unit.
On the larger triangle, the line EF has a length of 4 units.
Therefore, the smaller triangle was dilated by 4, since 4x1 is 4.
The triangles was flipped over the y axis.
This means that it was reflected over the y axis.
