Answer this question: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 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans.
The answer is 5.
