Question

the price of a train ticket consists of an initial fee of $5 plus a fee of $2.75 per stop julia has 21 and would like to travel 50 kilometers she wants to know the largest number of stops she can afford to buy on a ticket..... 1.which inequality describes this scenario?....2)what is the largest number of stops that julia can afford

Answer 1

s= number of stops

so we have the next inequality

$2.75s+5\le21$

we need to clear s

$\begin{gathered} 2.75s\le21-5 \\ 2.75s\le16 \\ s\le\frac{16}{2.75} \\ s\le5.81 \end{gathered}$

the largest number of stops that Julia can afford is 5
