Question

A prom ticket at RFA costs $110. John is going to save money for the ticket by walking hisneighbor's dog for $10 per week. He already has saved $33. What is the minimum numberof weeks that John must walk the dog in order to pay for the prom ticket?

Answer 1

Prom ticket costs $110

Money earned by walking his neigbor's dog: $10x, x is the numbers of weeks

He already has saved $33,

So the equation that represents what is the minimum numbers of week is:

`\begin{gathered} 33+10x=110 \\ 10x=110-33 \\ 10x=77 \\ x=(77)/(10)=7.7 \end{gathered}`

Rounding the number, John must walk his neigbor's dog during 8 weeks
