Question

Diana sold 336 muffins at the bake sale.Bob sold 287 muffins.Bob estimates that he sold 50 fewer muffins than Diana.how did he estimate? Explain.

Answer 1

He rounded 336 to 340 and 287 to 290. Then he subtracted 290 from 340, that's how he got 50.

Answer 2

Explanation:

Since we have given that

Number of muffins Diana sold at the bake sale = 336

Number of muffins Bob sold at the bake sale = 287

Now, here we are using the method of estimation i.e. rounding the integers to nearest ones.

By estimation, we get

Number of muffins Diana sold at the bake sale = 340

Number of muffins Bob sold at the bake sale = 290

So,

Difference between them is given by

`340-290\\=50`

Hence, Bob sold 50 fewer muffins than Diana.
