Estimate the answer by rounding as indicated. Estimate by rounding to the nearest ten.
72 + 46 + 26 + 95 + 33 = 272

272 = 280
Is this right?

No, it is 270.

It's 280. You round each one by tens though, you don't just round your final answer (and 272 would round to 270 anyway). 70+50+30+100+30=280
