Answer 1

18) In this problem they are telling you that the cost of the gifts are given by the equation:

`5g+15=140`

So to know the cost of each gift we can solve for g so:

`\begin{gathered} g=(140-15)/(5) \\ g=25 \end{gathered}`

So he has 25 gifts for each gift. So is B.

19) now the expression that represent the number of games is:

`4x-3=y`

So the correct expression is:

A) Lori owns 3 less games than 4 times the number of games that have nathan.
