A group of friends wants to go to the amusement park. They have $207.50 to spend on parking and admission. Parking is $5, and tickets cost $33.75 per person, including tax. Which equation could be used to determine xx, the number of people who can go to the amusement park?

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: what are the following choices
