Noah bought a computer cartridge for $28.50. Sales tax on the cartridge was 6.5%. What was the total amount that Noah paid for the
cartridge? ( I need this answer ASAP)

Total = purchase price x ( 1 + sales tax )

Total = 28.50 x 1.065

Total = $30.35

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
