The price of a gallon of unleaded gas was $2.85 yesterday. Today, the price fell to $2.79. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Also this is for twenty points.

Step-by-step explanation:

2.85-2.79 is 0.06

0.06/2.85 X 100 is 2.1% decrease

Percentage rounded to nearest tenth:

Step-by-step explanation:

Let P represent the decrease percentage

2.85 - 2.85×(P÷100) = 2.79

then

2.85×(1 - (P÷100)) = 2.79

then

2.85×(100 - P)÷100 = 2.79

then

100 - P = (2.79×100)÷2.85 = 97.894736842105

then

P = 100-97.894736842105 = 2.105263157895

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y
