Answer:

The correct answer is option B,

Total four service can be taken.

Step-by-step explanation:

Distance traveled by Josh outside the radius 7 miles\\

The cost of travelling 7 miles\\ outside the radius

= 7 * 2.25\\= 15.75\\

The amount remaining after paying for the outside travelling

= 200 - 15. 75\\= 184.25\\

Number of oil service than can be taken out of the remaining amount

= \frac{184.25}{40} \\= 4.60\\

Thus total four service can be taken

Svetradugi [14.3K]

Answer:

  • $52
  • this estimate is a little low

Explanation:

a) I might choose 6 1/2 hours and $8 per hour, so the estimated earnings would be ...

  6(8) +(1/2)(8) = 52 dollars . . . . estimated earnings

These values are purposely chosen so that one is a little high and the other is a little low, hopefully producing a closer estimate than if both numbers were high (as 7 hours, $8, for example).

__

b) Using 800 instead of 790 means the pay estimate is about 1/80 = 1.25% high.

Using 6 1/2 instead of 6 3/4 means the hours estimate is about 1/27 ≈ 3.7% low.

So, we expect the product of these values to be slightly low, perhaps by about 2.5%.

_____

<em>Comment on estimating</em>

If you can estimate the error in the estimate with some reasonable accuracy, you can use that to adjust the estimate to a pretty close value.
