Rebecca ran 4 laps at a time of 2.5 minutes per lap. She wants to decrease her total time by -0.20
minutes, with equal time per lap. Her goal is to change
her time for each lap by how many minutes?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

40% off the regular price is the correct answer.
