P

Home runs already hit + Home runs he( 1 ) needs to hit = Total home runs wanted

Home runs already hit = `X`

Total home runs wanted = `Q`

Home runs he needs to hit = `x`

`X + x = Q`

`x = Q - X`

Number of hours he( 1 ) babysat = `X`

Total amount of money earned = `Q`

Amount of money earned per hour = `y`

`Xy = Q`

`y = \dfrac{Q}{X}`

`P = \dfrac{Q}{X}`

person( 1 ) earned `\$P` per hour while babysitting.
