Question

skis cost $25 an hour to rent plue a $10 flat fee. The rental place takes cash only and Rob has $135 in his pocket. How many hours can he ski for?a) Let x beb) write an inequality in terms of xc) solve your inequality to answer the question

Answer 1

• (b)25x+10≤135

,

• (c)5 hours

Step-by-step explanation:

a) Let x be the number of hours he can ski.

b)

• Skis cost $25 an hour to rent, therefore cost for x hours = $25x

,

• Flat fee = $10

,

• Rob has $135 in his pocket.

An inequality that represents this situation is:

`25x+10\le135`

c) Next, solve for x:

`\begin{gathered} 25x\le135-10 \\ 25x\le125 \\ x\le(125)/(5) \\ x\le5 \end{gathered}`

Rob can ski for 5 hours.
