Question

You bought popcorn,p, and pop at the movies for a total cost of $9.25. The total cost represented by the equation C=3p+1.75. Find p, the number of boxes of popcorn purchases

Answer 1

The equation given is:

`C=3p+1.75`

Where C is the cost an p is the number of boxes of popcorn.

Since, it is given that the total cost is 9.25, we put it into "C" and solve for "p", the number of boxes of popcorn bought.

Hence,

`\begin{gathered} C=3p+1.75 \\ 9.25=3p+1.75 \\ 9.25-1.75=3p \\ 7.5=3p \\ p=(7.5)/(3) \\ p=2.5 \end{gathered}`

p = 2.5
