Answer:
8:
Let's round each of the number to the nearest 10.
will become
, since it's near to it.
And
will become
.
So, the product will be:
![30* 70](https://img.qammunity.org/2023/formulas/mathematics/high-school/3zz276dv1k3q9c93w3tbb29rxhtcybu1dv.png)
We can calculate this to be:
![2100](https://img.qammunity.org/2023/formulas/mathematics/college/8bln8i9gn8vus92lk0smnata3y4vytes84.png)
Since we rounded all the numbers to greater numbers than they were, this product is thus an overestimate.
9:
Let's round each of the number to the nearest 100.
will become
, since it's near to it.
And
will become
.
So, the product will be:
![500* 300](https://img.qammunity.org/2023/formulas/mathematics/high-school/430gtxe9opc7wx63fu57vpu0lyti9hc074.png)
We can calculate this to be:
![150000](https://img.qammunity.org/2023/formulas/mathematics/high-school/ugb2vx91qymxgqiq0tzqxkxawx5vfl8u3z.png)
Since we rounded all the numbers to lesser numbers than they were, this product is thus an underestimate.
10:
Let's round the price of the bowl to the nearest 10.
So,
will become
.
So, the total estimated price of the bowls will be:
![10* 132](https://img.qammunity.org/2023/formulas/mathematics/high-school/3z7q0o5v7e3gfgk3zlcg3rfhdbv046ohvd.png)
![=\$1320](https://img.qammunity.org/2023/formulas/mathematics/high-school/9qiq9436c8ok3w9f4mpansxfbdta5indq1.png)
Since we rounded the price to a lesser value than it was, the overall product is an underestimate.
