2. Sol went to the store to buy tomatoes. They were $1.89 per pound: Last week, the price per pound was 30% lower. What was the price of tomatoes last week?

1.323

Step-by-step explanation:

We can find 30% of 1.89 by multiplying: 1.89 x 0.3 = 0.567

Then, we must subtract: 1.89 - 0.567 = 1.323

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
