Which rounding strategy will result in the most reasonable estimate for the expression −148+297+−546+151+48? −150+300+−550+150+50=−200

−100+200+−500+100+0=−300

−100+200+−500+100+0=−900

−150+300+−550+150+50=−1200

-150 + 300 - 550 + 150 +50 = -200

Step-by-step explanation:

I rounded to the nearest tens place for each number.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
