Answer:
$11.25
Step-by-step explanation:
You give the farmer $60.00 and you subtract $48.75 = $11.25
Therefore the farmer gave you $1.00 more.
The group bought 17 hot dogs.
The answer is B. 0.25 inch. Lets multiply all of them by the same factor. Since A. and B. have 3 decimals, lets divide all numbers by 1000: A. 0.026 * 1000 = 26, B. 0.25 * 1000 = 250, C. 0.24 * 1000 = 240, D. 0.025 * 1000 = 25. So, by comparing the whole numbers, it can be concluded that the biggest steel rod is B. 0.25 inch.

And we can recognise the same integral, so.
And then,
Thanks
