10. 903.6 - 25.1
Exact
Estimate:
11. 760.38 +0.38
Exact
Estimate:

10. 36 (exact answer), 30 or 30.16 (estimated answer).

11. 2001 (exact answer), Undefined, or 1900 (estimated answer).

Step-by-step explanation:

For number 10, the exact answer is 36 and the estimated is 30 or 30.16. Why?

-To have the exact answer we have to divide 903.6  ÷ 25.1 = 36.  

-To have the estimated answer we have to round 903.6 and 25.1, as 903.6 is close to 900 and not 1,000, and 25.1 is close to 30 and not to 20. The equation is 900  ÷ 30 = 30.

-To make sure that the exact answer is correct, we have to multiple 25.1 and 36 = 903.6.

-To make sure that the estimated answer is correct, we have to multiple 30 and 30 = 900.

-But there's a problem, they can be two answers for the estimated answer 1). 30, and 2). 36.16. Process: 904 ÷ 25 = 36.16. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.

For number 11, the exact answer is 2001 the estimated is 1900 or Undefined. Why?

-To have the exact answer we have to divide 760.38  ÷ 0.38 = 2001.

-To have the estimated answer for the undefined we have to round 760.38 and 0.38, as 760.38 is close to 800 and not to 700, and 0.38 is close to 0 (0.00) and not to 1 (1.00). The equation is 800 ÷ 0.00 = Undefined.

-To make sure that the exact answer is correct, we have to multiple 2001 and 0.38 = 760.38.

-But there's a problem, they can be two answers for the estimated answer 1). Undefined, and 2). 19. Process: 760  ÷ 0.40 = 1900. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.

answer: i guess 5 units?

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
