Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
Half the cans collected by Martha is 90/2 = <T>divide(90, 2)=45.0
So, Diego collected 45 + 10 =<T>add(45, 10)=55 cans.
Martha and Diego collected 90 + 55 = <T>add(90, 55)=145 cans together.
Thus, they need to collect 150 - 145 = <T>subtract(150, 145)=5 more cans.
