Question

You earn $20 per hour landscaping a yard. You pay $1.50 in bus bus fare each way. How many hours must you work to earn $117?

Answer 1

Assuming you do it all in one day:

Explanation:

Earnings=hours x $20 minus busfare (2 x $1.50), or:

`E=$20xxh-$3=$117`

Add $3 on both sides to keep the balance:

`$20xxh-cancel($3)+cancel($3)=$117+$3=$120`

`->h=(cancel$120)/(cancel$20)=6` hours of work
