`29`

Show Worked Solution

`text(Strategy one:)`

`text(Try possible numbers,)`

`text(24 Curtly − 23 Alvin ⇒ 1 difference)`

`text(25 Curtly − 22 Alvin ⇒ 3 difference)`

`vdots`

`text(29 Curtly − 18 Alvin ⇒ 11 difference)`

`:.\ text(Curtly picked 29 apples.)`

 

`text{Strategy two (use of algebra):}`

`text(Let Alvin pick)\ \ x\ \ text(apples)`

`text(Curtly picks)\ \ x + 11\ \ text(apples)`

`x +x + 11` `=47`
`2x` `=36`
`x` `=18`

 

`:.\ text(Curtly picks  18 + 11 = 29 apples)`
