Question

What is the maximum number of games Dee can buy from Taylor's Department Store if he wants to keep his total cost to no more than $150? Show your work. (Goal 9) .

Answer 1

We assume the next variables

x=number of games

y= cost per one game

the inequality is

`xy\le150`

the sign equal less than is used in this inequality because the total cost can't be more than 150

in order to know how many games she can buy, we need to isolate x

`x\le(150)/(y)`

If y= 20 for example

`\begin{gathered} x\le(150)/(20)= \\ x\le7.5 \end{gathered}`

she can buy 7 games if the cost per game is 20
