Question

Using inequalities to solve problems 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. Let S represent the number of stops that Julia buys. 1) Which inequality describes this scenario? Choose 1 answer: A 5 +2.75 S < 21 в 5 +2.75S > 21 5 +2.75. S < 50 D 5 +2.75.S > 50

Answer 1

The inequality would be letter A.

`5+2.75S\leq21`
`2.75S\leq21-5`
`2.75S\leq16`
`S\leq5.81`

The largest number of stop that Julia can afford is 5
