Question

John has a job selling souvenirs on a football stadium. He earns $10 per game plus $0.25 dollars for each souvenir he sells. How many souvenirs does John need to sell during a total of $35 for working at one game?A. 50B. 100C. 180D. 360

Answer 1

He needs to sell 100 souvenirs

Here, we want to know the number of souveniers John has to sell

Let the number of souvenier he sold at the game be s

At a rate of $0.25 per souvenier, the amount earned on souveniers for s souveniers will be;

`0.25* s\text{ = \$0.25s}`

Now, if we added this to the amount he earns per game, we will have the total $35 earned for working at one game

Thus, mathematically;

`\begin{gathered} 0.25s\text{ + 10 = 35} \\ 0.25s\text{ = 35-10} \\ 0.25s\text{ = 25} \\ s\text{ = }(25)/(0.25) \\ s\text{ = 100} \end{gathered}`
