Julia went to the movies and bought one jumbo popcorn and two chocolate chip cookies for $5.00. marvin went to the same movie and bought one jumbo popcorn and four chocolate chip cookies for $6.00. how much does one chocolate chip cookie cost?

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

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
