Elizabeth and Lauren sold cookies for a school fundraiser and made $1,316.70. Together the girl sold a to total of 831 cookies. Elizabeth sold chocolate chips cookies for $1.50 each, and Lauren sold peanuts butter cookies for $1.65 each. How many cookies did Lauren sell?

468

Step-by-step explanation:

831-x would be the equation to find the amount of peanut butter cookies. You'd plug this into the equation to find the amount of cookies in relation to money meaning your equation is 1.5x+1.65(831-x)=1316.7. You then simplify and solve to find 468

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

- 70
