Scott wants to tip his taxicab. If his commute costs $15 and he wants to give the driver a 20% tip, what is the cost of the tip?

$18

Step-by-step explanation:

If $15 = 100%, add 20% + 100% = 120%

120% = 1.2

So, multiply 1.2 × 15 = $18

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
